Here's a third screenshot: look at the Y coordinate, notice how it's at 99, close to 100, so I guess if you get higher, that's how high you'd be when you change the Y coordinate for how high Lava Oceans can be.
2 Things:
1: Thanks for saying that the Lava Ocean is buggy already 🙂
2: The chunk specific question: Yes, here's another screenshot.
Probably some pixel they accidentally added to character. Not a game breaking bug, but still interesting.
I guess there IS a fix Mojang needs to work on 😃
True. This is not even a glitch at all. All it is is just generation. Sometimes it derps, sometimes it's normal.
WAIT! I just realized the reason this glitch happens. If you go into third-person and do the method about walking on the edge of the wood, it looks like the player isn't on the wood at all. The game thinks your not on wood. Then, Minecraft say's that I'm not on a block and that I'm making no noise.
As I said in the desc., "I was playing around with Custom Worlds", but I did not make a default world.
