Ever since the 1.3 updated I started to get problems with the survival games server. When ever I shift click items in my inventory or even slowly drag the items from the chest, it disappears from my inventory/hotbar in a matter of seconds! This even happens we I am completely alone too. Also, a newly encountered problem was when alive players where invisible to me and I was invisible to them as well when i was still alive. Does anyone know how to fix these problems?
