I logged in with fullgeared character on experimental, my gear start to despawn from my character and after a few seconds it spawned back in. When I tried to drop an item it simply vanished. I found out after meeting my friend that other players couldn`t see me or hurt me, but I could punch people and zombies and sometimes when my gun didnt despawn I could still shot and kill Zombies or Players. At the end i got frame drops everytime my gear reappeared. It got worse and worse til my game crashed.
