Hey there,
I can run around the world perfectly fine.
I cant equip anything.
I cant interact with other players or zombies
In the Playerlist all other players have bandwith, ping & desync: 0
I tried jumping of buildings, but i cant die like that.
I asked my friends, they can see my body at the location i logged in from.
And i can change spawnlocations by just walking around and logging out and in again. Then my position for other players changes as well.

This bug happened to me twice at the northern airfield near the Firestation.
