It happens a lot for me while I'm on ladders but not sure if that's the same thing player_8008 was talking about but either way it is a bug. Also call of the void dev if you see this I just gotta say that you did an amazing job on the update and made a masterpiece of a game.
I'm giving another crack at fixing this now. I can probably fix it for 90% of the times it breaks the game, but there's so many edge cases with physics.
So glad you've enjoyed the game! (apart from being stuck in walls)
sorry i am late to reply but yes i was on a ladder and the few times it happened, either somebody died and i got stuck on a corpse, or i got hit and got stuck in the wall while going up the ladder
