The way to find that out is to add one of them and log back in. Not bugged ? Okay, now add another one ... ? Not bugged .. etc
Once you find the one that bugged out on you. Turn the other ones off and try it again. Just in case its a combo bug between 2 or more of them
If it turns out to be my LDB plugin I'll add it to my growing list of addons to fix rofl. If it works out to be one of the others just post on their pages and here so people know it could cause problems. I don't have Config_GUI or the DK skin so they're possible candidates.
