Btw when i take a "Survivor" in my menu and click on customize and i change the outfit and name and press on quick start, i come to the serverbrowser. Well thats normal but when i click on "back" and see my renamed Survivor in the menu and then change the Survivor with ">" or "<" the character is gone. Some old characters with spawn equiment are still there but the new one is always gone. Tried it serveral times, i hope it helps.
And my girlfriend can join any server from our home so its not a router/provider problem i guess^^

I actually can´t join any Server with any character.. :( Always get kicked with the database lock message. I tried serveral times with 5 minutes break. Changes nothing..
Good luck to fix that.
