Here's a bug: World 8's gimmick doesn't get undo'd properly.
Yeah, I think there's a bug that happens in 8-A in very special circumstances. If there's some other bug that happens elsewhere though and still doesn't get undone properly, do tell me the steps to replicate it so that I can fix it properly later.
when does it happen?
