This issue is happening in Cata Classic on my character Maricutie on realm Gehennas PVP. I can’t dismount at all from my mount. I did /disableaddons and it didn’t help. I tried character unstuck and it didn’t help and even dieing did nothing. If I mount I get stuck on the mount and neither attacking or setting the auto dismount in flight setting or joining a dungeon did not dismount me. I can see myself try to dismount but then nothing happens and it says “You are mounted”. I also tried right clicking the mount from my buffs next to the minimap and it does nothing. The only way I found that I can get off the mount is entering a building but then if I get on the mount again I’m stuck again. I also tried restarting the game and relogging. I think I got stuck after trying to take a flight point while mounted in Outlands. I even tried taking the flightpoint again and it didn’t help.
Edit: I just logged onto another character (Vexanu on Firemaw) that was in Outland and I just got the same exact problem on him aswell now but it is only happening with the Kalu’ak Whalebone Glider mount (same mount im stuck on on the first character i talked about).
Edit 2: It seems to be a problem that happens on all my characters, only with the promotional mounts that I own (Kalu’ak Whalebone Glider, Nightmarish Emerald Drake, Avatar of Flame etc). Mounting a normal Wind Rider does not have any issues with dismounting.
