After transforming a few times and changing back I fall through grounds, all grounds after changing back to a mouse but others dont see you fall just dissapear

that always happens to me, i cant tell u what is it, maybe we r laggy.
Or if no, maybe tfm has temporar bugs.
It happened a few time ago, when if u put a plank on another one they started bouncing crazily like anvil gods.
If its a tfm bug, dont worry then, the admins will fix it as soon as they can

This bug, I turned into an anvil then jumped, Ifell through the ground. D:

;-; I transformed IN THE AIR and i just disappeared, presto. Imma phantom.

It is basicly due to lag, people have been receiving this bug many many times, you may get this bug, but so far there hasn't been a solution to the problem yet (According to the forums.), so you may just have to deal with it until one of the administrators get to fix the bug, but otherwise, there's no other option for this problem.
