I have had three characters, the first had no bugs at all, literally none (before patch 1.2). The second one seemed to have none, didn't play that one for long though (after patch 1.2). The third one (after patch 1.2) has loads of them, no gamebreaking ones yet but loads of little ones, lag, a few colour problems, game freezes sometimes for a second when I talk to people/scroll the menu etc.
Anyone else felt this? Might just be the patch though.
