I found out that it was (apparently) optifine's fault. Removing it made the world playable again. At least I think it was optifine's doing, not sure if any other factors counted in towards the crashes.

ahh, right. Optifine is messing with vanilla code here and needs to adjust to the latest forge changes not to break this, that's definitely on them.
