"I'll freeze and hover, sometimes in mid air and sometimes on the ground. It lasts for about 3-4 seconds, and in that time if I try to move or jump or anything it's like I have a short elastic band attached to my player and I keep snapping back instantly, I can't move very far either before it snaps me back (so it appears like I might be floating in the air, but I am actually falling and snapping back to mid air very quickly). And after 3-4 seconds, it stops."

. there is a simple answer to that (trust me, i'm a pro with this problem

), it's that little prick
