Hey. I've checked the Warcraft Forums and looked over these forums for this question as well as looking at the ingame FAQ and can't seem to find it. I apologize if I missed it somewhere however, I did look. 8)
I've also tried to re-Mazzlefy and have had a couple pretty good Mazzlegasms due to it but none have fixed the issue.
I was in an ill-fated BFD run (3 hours...wtf...) when I noticed that some of my bars had moved and took their bindings with them.
It's a pretty minor thing and if I have to live with it, I can. It'd just be nice to swap them back.
Thank you for your help.
//edit: Well, I mazzified and relogged and it fixed it. If someone can tell me what causes it, that would be super so I don't do it again. lol
