switch bugs

waring, i don't know the affected version! altho, it's 1.16.

here are the bugs: 1: if you have too many chickens in a 1x2 hole, they can't be killed by lava.
2:on a map in a relm, sometimes your player marker will switch to a 3d steve head for a few seconds.
3: also in a relm, sometimes there's a white box that can be moved thru, but can only be moved by pistons.
