- [Narrator] 15 Minecraft bugs
that Mojang never patched. Over the years, Minecraft
set plenty of glitches. And most of them get
fixed in a later update. But today, the glitches were covering Mojang either hasn't fixed yet or refuses to even address them. At this point, we might
even call them features. And hey, the YouTube penguin bet me that it's impossible to subscribe to the channel before it
crosses this icy lake. So to prove them wrong, water that red sub button down below. It's free and it helps out a ton. Number one. Now, as a little thought experiment, I want you to look at this mob and try and guess what the glitch is. Go ahead, what do you
think is wrong with it? Do you see it? Do you see the glitch yet? Well, I'll tell you that the glitch is that this is actually
supposed to be a pig. Or rather, it was. See, creepers actually came into the game because of a failed pig model. Sure enough, Minecraft's
most iconic mob came from one of the most mundane. So if you wanna talk about the quintessential
glitch that became a feature, this might be Minecraft's most famous. Or, in fact, this might be one
of the most famous glitches that ever became a feature in history. And thank God it did, because honestly, I cannot imagine Minecraft
without a creeper. I mean, it's not often
that your failed 3D model ends up on this much merch, just saying. Number two. So this is a weird one
because, in fairness to Mojang, they have tried to get rid of
this feature once or twice. And that of course is the
many different x-ray bugs that exist in Minecraft. While I personally
remember back in the day when I'd try to light up caves, I'd push a redstone block into my head, composters are way more of
the popular option these days. And while, sure, these
glitches don't exactly work like the x-ray features
and hacked clients, they aren't exactly intentional. But, if for the time
being, you wanna use this while Mojang still has it in the game, all you gotta do is push
these different blocks into your player model and just like that, you'll be seeing every unlit cave and, who knows, maybe even
some diamonds down there. Number three. The Redstone community is one of the cornerstones of Minecraft. And for good reason, they
do a lot of great stuff. But it's weird to think that
so much of the community, at least in Java, is
built around a glitch. The community calls it Quasi Connectivity and what this refers
to is a bug in the code that allows for piston, as well as dispensers and droppers, to be activated when
blocks directly above them or diagonally above them
receive a redstone signal, even if they're not getting one directly, which sure enough means that we're able to power pistons like this, even if it doesn't make direct sense. And if you want any further proof that this is unintentional, it doesn't exist in Bedrock Edition. It's just the Java people who
get to play around with this. And for all of you playing
Bedrock, I hope for your sake it gets added in intentionally, someday. Number four. Minecraft has a couple of different blocks that are famously not able
to be broken in survival. And while that's the
case with command blocks and End Portal frames, I think all of us think to bedrock first. But even though our pickax
might not do a great job of trying to get through this block, that doesn't mean it's
not possible in survival. Because strange as it is, it actually seems like it's
getting easier and easier in every coming update
to get rid of bedrock. While in the past, I
remember having to do this through different long redstone circuits and TNT minecarts and such, from now all the blocks
that you need for it could fit easily in a hop bar. It's just getting that simple. And hey, I'm not complaining. It lets me build my nether
hub without any kind of Ghast. I see that as an absolute win. Number five. One of the monumental discoveries
that shaped the landscape of Minecraft redstone
has to be these block update detector switches. These BUD switches, as the
community likes to call them, are such an essential way
to how we play the game. I mean, up until 1.11, it
was the only way to tell if a block got updated. And folks, it doesn't take
a lot of redstone know-how to see just how useful one
of those could be farms. Which is why, luckily for us, Mojang added these in officially through the form of observers. Now that's not to say that
the original BUD switch isn't still in the game. As you can see here, both
are working the same way. But what we do have here is convenience, which I think is how Mojang
actually sought to replace it. Because if you asked me if I
wanna build this whole circuit or just place down one of
these blocks with a face, I'm definitely taking my
option with a straight face. Number six. Now, of course, with Minecraft
wonky world generation, you're sometimes gonna
see non-flowing water. But that's not all that exciting, 'cause as soon as you block update, it's just gonna pour over. That is, unless you use this trick using sea grass and bone meal. Because apparently, that
bug hasn't been fixed yet. With a setup like so, you
can place a water bucket at the top of a two block
structure and then throw in some of that sea grass right there at the bottom and bone meal it. Just like that, remove
the blocks on the sides and you've got your very
own non-flowing water. And while that's cool, that's
not even the last part. Because as you can see, no block update is actually gonna get this to flow over. Somehow, the sea grass just keeps it all in that one cubic meter. So is this game breaking? I guess technically, but
it's not exactly overpowered. Number seven. Anyone who's ever messed around with the enchanted books in Minecraft knows that certain things
are mutually exclusive. So for example, the way that it is in the current versions of Minecraft, you can't put together
all the protection types onto one piece of armor. But strangely so, for a
brief period of time back in 1.14, that wasn't the case. So after it got reported
in the bug tracker, most people thought
that was the end of it. But that's not the end of the story. Because as you can see, if you
made this armor back in 1.14 and then just continue to play through all the different
versions of Minecraft, then, as it goes, that
armor didn't get updated and it still functioned
as a piece of armor with all the different protection type. So if you played Minecraft back at 1.14, you definitely have
something to show for it. Number eight. Unless you build something
in the spawn chunks, then most of the time,
it's not gonna get loaded if you're not there. At least, that's how
it was supposed to be. Clearly, there were plenty of different, unintentional methods to do this. And while most of us thought that every time one of these popped up, Mojang was just gonna squish it like that, strangely enough, it actually
became an intended feature through the help of nether
portal chunk loaders. The setup that we have
here is super simple. All that's happening is
that an item will get sent through the portal every 300 ticks. After that, the item comes back and then it goes through an infinite loop of loading the different chunks. In a lot of ways, this isn't too far from the way that it
worked in bugs in the past. And I think I speak for everyone
in the technical community when I say that there was a
lot of rejoicing when we knew that this was in the game to stay. Number nine. While the 1.14 Village and Pillage update brought along a ton of new features, one of the famous ones was crawling, which is if you set yourself up like so, normally through the help of a trap door, you can actually crawl
in one block spaces. This is very cool to see. And while you could say
that it was based on some of the different modded
implementations in the past, as it turns out, it really came into play when 1.9 brought along the Elytra. There, you could pull it off
as some form of side effect, which was pretty neat. And then when we had
swimming introduced in 1.13, there was multiple different
ways to pull it off. It just made sense to
add it into the game. Thankfully, now we have
a fully intentional way to get into our one block spaces. And more importantly, I think
we really gotta pay respects to 1.13 and 1.9 for
helping along with this. Number 10. While blaze spawners make
for a pretty popular way to get plenty of EXP in the nether, anyone who's ever messed around with a fully automatic gold farm knows that the zombie piglins
can offer their fair share. But one of the reasons for that actually bases around a glitch. You see, many people know that the way that their aggression
system works is that, when they get attacked they
actually get the other people around them angry as well. But what's interesting is that if we kill some of those
auxiliary agro pigmen, even if we don't touch them
at all, they still drop EXP. And this is what allowed us to make fully automatic AFK gold farms for EXP in the nether. And now, for the foreseeable future, this is now working as
an intended mechanic, which is great for both
us and our mending tools. Number 11. If you've ever messed around with the different world
generation settings, then you're all too familiar with the idea of an amplified terrain. And if your computer can handle it, it's definitely a spectacle to go and fly around one of these things. Which is why it's all the more curious that something so beautiful
was created on accident. As Jens describes, while working
on some terrain generation, they accidentally messed
up the coordinates. So not only did Jens gets to
add in a very fantastic feature into the game, but nowadays
that they're working on the new mountain generation for the Caves and Cliffs update, I'm sure some of those
terrain generation mishaps are finally coming in full force in the intentional method, giving Minecraft two very different, but also equally beautiful ways to touch up to the top of the sky. Number 12. For a long time in Minecraft, boats had been somewhat
of a laughing stock. And while Mojang has thankfully
ironed out the rough spots to make these work better in water, if you've been playing
Minecraft long enough, then you know that they do their best work on an ice highway. This method makes for
one of the fastest ways to travel in the game. And while their add propulsion might seem like it's working unintentionally, according to the words right
out of Mojang themselves, it actually is working as
intended on the bug tracker. Which is definitely fortunate for us and for our nether homes. Because now we get to
travel those thousands of blocks in the overworld
not only with style, but also with plenty
of speed to back it up. Number 13. It's weird to think about that when Elytras were
first added into the game, there wasn't a way to make them fly. Rather, they were way more
of a gliding technique. That is, until players found
out the unintentional way of putting their bow to use. As you can see, when you're
flying around with an Elytra, all it takes is hitting yourself with a couple of punch
two arrows and boom, you're flying off into the indefinite. Now, even if we wouldn't
exactly call this a bug, it definitely wasn't
what Mojang had in mind. So as a response in 1.11 Snapshot 16W50A, that's when we got the
intended way of doing this, which was of course firework rockets. And thank goodness for that because the last thing I'm trying to do while I'm exploring my
world is land a couple of bullseyes on my head to
keep myself going forward. Number 14. Minecraft's world
generation can famously lead to plenty of weird and wacky sites. And among those, arguably
the most common one that you're gonna see
is different floating sand and gravel blocks. Now, of course, these are
supposed to fall to the ground. You can see that when
you block update them. Now, initially this was treated as a bug, because obviously that's not
exactly what you hope for when you make a world generation engine. But later on in a Minecraft's Life, Mojang made the very clever switch-a-roo making it an intended feature. Because as you can see, if
we just add in dust particles falling from the floating blocks, now it's alerting the player of cave-in. Repackaging this bug is
way more of a mechanic. And honestly, while I
still think these blocks being suspended in air is pretty silly, I have to commend Mojang
for their different way of looking at this. Number 15. Item duplication is normally
a conversation that's sure to split a couple of players
into different sides. But while I'll leave that
discussion for them to hash out, I think the form of item duplication that most of us are totally fine with comes from one of these,
a TNT duplication machine. It still hasn't been patched out, even though Mojang fully knows of it. Because the way that the
story has gone so far is that Mojang has patched
it out in the past. But since in the Java
edition, there's currently no way to make moveable tile entities, meaning that you can't move TNT dispensers on a flying machine,
there's no intended way to replace what the TNT
duplication machine does. And honestly, if I've gotta
give on my TNT duping fun to have movable tile entities like chests and dispensers and droppers,
I'm completely fine with that. And with that, folks, glitch
that sub button down below and have a good one, all right?
