was your pen double walled? any performance issues?

the only thing i can think of is either something got in there and murdered them (there would be drops if this was the case) they escaped through a random error that lost their location briefly due to any number of things. if your friend was closest though, it might have been a desync freed them.

they really like to hug walls far some reason, its kind of annoying and immersion breaking, so typically if i can the food sits in the middle of the pen to keep them off the walls.
