I was playing on Lua Defense with a random and we had just gotten past wave 10 when the map dropped down to the third floor. I went down, but I didn't see the other guy drop down with me. When I looked up after a respite, his name ID was well above me in some corner of the map either on the top or second floor. I asked him why he was still up there and he said he was right next to me. In addition, he was unable to cast any abilities, but he was somehow imperceptible to the enemies. Dealt damage
