Details: Character was found to be using a Third-Party application that allowed him/her to make movements that are not possible through the standard game-client. lol wtf that even mean
The other day I was using honorbuddy with Kick's profiles for Borean Tundra in northrend. When it came time to move into Dragonblight, the profile sent me via my flying mount into Wintergrasp. Something happened then, I think it was a combination of the studder that happens when you load into a new CRZ and the auto dismount bug with Wintergrasp, but next thing I saw was my character flying w/o a mount (more like swimming through the air) to the next quest hub in Dragonblight. When I landed I was still moving around under a speed boost. I was able to interact with NPCs, take quests, etc. and I was able to jump into the air and swim around at light speeds again. I stopped the bot program at that time and it didn't fix my character. I had to relog before my character was once again bound by the laws of physics. TL;DR weird shit happens, don't go AFK for long periods of time would be my advice.
