During the MoP Remix, I created a Pandaren Rogue who was on the Horde. I finally was able to login yesterday, 8/21 and went to choose that character, expecting to be in Orgrimmar or another Horde territory and found my character was in Stormwind and now Alliance. I have no idea how that happened. I even have achievements for Alliance when I know I did the Horde storyline.
LOL! These bugs are getting entertaining.
