While the new update may have fixed many bugs along with adding in some great new content, I find that when I swap around between servers when they crash, restart, etc. that I'll start out as a new character. It's not because I'm going from regular to hardcore, it even happens going back to the same server sometimes. I randomly lose my characters, but I also reacquire older ones as well. Playing earlier today, I somehow got back a character I had from two weeks ago? tl;dr - I have like three characters across similar servers, and it's impossible to tell which server might give me which one.
