So I've been playing for a few days now, and while I'm logging in under my old nickname, I haven't seen my old characters - I had a quite extensive list, which has now only the three new ones I made.
It doesn't bother me - I want to play only new characters anyway, and it always bothered me that characters weren't deleted here, and that I had to hunt around in the huge list - but someone might be running around with my old characters, which does bother me a bit, and probably means they don't have much goodwill towards the server.
Maybe it's related to me having new CD keys, as I bought the game from GOG to come back? My login is gfgfgfgfgf, if anyone want to check this out. To be clear, if you figure it out, I'd rather not have the old list of characters back, but it might be a bug you want to look at.
Cheers!
