So the server just updated and when I logged in I proceeded to jump on a chest. When I did so it seems as tho it acts as if I'm on a ghost block in the sense that I would be kicked for flying. I am letting people know now before it becomes some huge issue, DO NOT JUMP/WALK ON CHESTS.
Now have discovered its any block which is shorter then a full block.
Ex: Enchanting table, Bed, Chest, ect.
Froob update nocheat plugin and its all fixed so ignore this post. xD
