Bug description
I'm using identity-1.11.9-beta-1.16.5, and whenever I'm morphed into another creature, it seems I can't crawl or sneak properly. That is, I do get slowed down by the act of entering a crawling or sneaking state, but I can't crawl under one block spaces/start suffocating, and sneaking doesn't allow me to sneak under spaces less than two blocks tall.

Game log:
Sadly, hastebin keeps giving me a "something went wrong" error message when I try to save my log to it, so I can only provide it as a text file.
