Slimes being able to go through blocks should be a thing tbh. I mean, it's a slime. It CAN do that

Leaf decay broke like 5 times in early minecraft

Reading patch notes mentioning "leaf decay disabled/enabled" was very funny after a while.

I guess the sand being placed on snow layers is a 1.20 bug too :P

- Bug 13 - I feel like this was maybe intentional (as kind of a joke), after all, the oak door has 4 holes for windows.
- Bug 16 - This also caused the player to interact with the block behind the stair (i.e., trying to break the stair, only to break the block behind the stair).
- Bug 17 - This was actually by design in the early version due to how block rotation was coded. They would face "in front of" the existing block on all 4 sides (the weird hitbox was probably a side-effect of this).
- Bug 50 - This is my favorite audible bug, holding shift while building something, then releasing after to hear compressed sounds. (I think it would even crash on occasions)
- Bug 76 - I wonder if this was actually intended at one point. I mean, they are squishy slimes...
- Bug 84 - That's the famous Minecart Booster Track, where all you had to do was ride next to an adjacent cart.
- Bug 87 - I always thought this was a normal generation (like the mixed grass/stone terrain generation).

Here's a few more that I've noticed playing the old alpha version over the years -
- There was a bug where iron (or all ores?) generated less in one quadrant of the world.
- Items falling onto farmland would destroy the farmland.
- Walking on farmland destroyed farmland.
- Sometimes placing a block would update farmland within that chunk.
- Lava had the same weird hitbox as water, meaning you could burn yourself standing in the corner of a block.
- It was possible to place a stair within yourself in some circumstances.
- There were occasional stutter bugs where the player would become stuck and the screen would shake until the player backed up.

Also, I thought sub-chunks were added in 1.9.

Making cakes with buckets of milk also consumes buckets if i remember correctly

The timing and your delivery of the bugs makes me fondly recall Sethbling, I’d like to thank you for that.

3:04 this bug still exists in modern minecraft

As someone who plays primarily alpha I'm almost constantly reminded of most of these bugs...

Maybe you should contact the developers

i have a "wealth" of knowledge on how the old versions work inside (and have even fixed some of their issues, such as one you didnt mention about stepping up blocks that ive demo'd on my channel) so i can espouse on why some of these happen.

relogging while sneaking causing phasing is due to how the sneaking animation was implemented. it abuses the "y slide offset" system thats used for smoothing your camera when stepping up blocks. sneaking adds a constant negative offset to it, which affects your real y coordinate. this normally isnt much of an issue since the game usually relies on your bbox for collisions n' stuff (the two are separate long story), but when saving/loading, the game only uses your xyz, which when sneaking, is technically in a lower block, thus you log in inside one.
(edit: okay to be anally truthful, at this point in the game, your XYZ coord is actually at eye level because jank spaghettii involving the camera being centred at the player XYZ, but when you log back in your hitbox is created inside of a block around that eyeline XYZ, and you dont collide with blocks you already intersect, so the effect is the same)

speaking of jank collisions, being able to hit through doors was not an intentional mechanic. this actually occurs with any block your head can be in, most annoyingly noticeable with torches. i still havent figured out _why_, but i think its a similar reason to why stair hitboxes are so fucked.

the slime phasing in the blocks make sense

First time i ever heard the audio glitch caused by going down stairs i got a little spooked haha

[gareth]

It’s a shame it’s in this state. If only there were future versions that fixed these issues or added more features 😢

Incredible video. We need more Golden Age themed Minecraft youtubers like you and Paladin Ryan.

my favourite is by far the on-fire minecart, looks sick af

I think "all 7 of these blocks render larger than normal" could all be compiled into one entry
When you say it counts as a separate bug for both wooden and stone pressure plates, you're splitting hairs

[greffen]

I still feel like the subchunk invisibility or stairs and fences is so cool. happy to see another Jy video :D

I vividly remember loosing my first Minecraft house due to 012, setting fire to my wooden house through the door, and with they speed of fire spread back then, it was just lost.
