Using Noble Mark on an enemy and then mounting your war-steed can bug you out really bad. I tried it today on Bugud and I found that all of my skills were greyed out and I could not dismount. I thought relogging would fix this but it only made it worse. Nothing happened when the logout timer ended so I logged out again using the Exit Now button, but this got me stuck at the character selection screen where it tried to finish logging out for five minutes. Restarting the client didn't help either, now I'm stuck at "Cleaning Up Old Connection" when I try to load in. Looking back I guess I should have just run into some mobs and let them kill me.
Any advice on how to fix this?
