Today I started the game on my laptop (not my primary PC) and after logging into the server I had a new character.
Interestingly, I had my original character in the opening menu. But when I logged in (to the same) server as last time, I suddenly had a fresh spawn. Where could the problem be? I think I have the steam cloud turned off on my primary PC, but according to what I've read, the character data is stored on the Dayz server, so that shouldn't be a problem.
It wouldn't bother me, but I already had a fully equipped character and, of course, some kind of relationship with it :D
