MC-53531(Custom Worlds) Chunk Generation
This probably was put up already by some, but I was playing around with the Custom Worlds option, and I had Lava Ocean, Ocean raised to 100, and set Biome to Extreme Hills, and got some chunk generated pieces from what looks like a regular Ocean biome, with Ice because of the Extreme Hills as a more hilly form of Taiga, but they spawned in my world. Any reasons why this happened? Let me know, and thanks

If some of the other bug reports from today are right the lava oceans replacing regular oceans is broken. Also ocean water is a special type of water that doesn't check the blocks beside it to see if it can flow into them when first generated (to avoid extreme lag). That's why ocean water can just hang like that. Not sure if it explains those rather sharp looking cliffs however. A biome change shouldn't be that straight should it? Does it look like it's chunk-specific when you look at it from other angles?
2 Things:
1: Thanks for saying that the Lava Ocean is buggy already
2: The chunk specific question: Yes, here's another screenshot.
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.
Did you previously create a save with the same name, which used normal generation, then replace it with a customized world? If so, that's a known issue.
As I said in the desc., "I was playing around with Custom Worlds", but I did not make a default world.
