Hello,
I logged in to my warrior (L26) in Westfall this evening and when I tried to move I got stuck. The character is continuously running on the same spot which means that logout/unstuck/HS is impossible to use.
I got summoned by a Warlock to Ironforge but I had the exact same problem as soon as my character teleported there as well.
I also tried logging in to my level 3 Rogue in Northshire Abbey and upon trying to move that character also runs continuously on the same spot.
Finally I created a new level 1 Night Elf and I was able to move with that character.
Tried logging back onto my L26 in Ironforge but the problem remained. It almost looks like everything's not loading since every exit/tunnel etc in Ironforge that are about 60-80 yards away just seems to be a "blue wall". The players that pass by close to me seem to be lagging. They "teleport" 3-4 yards instead of moving smoothly.
Fyi: I tried relogging with no add-ons at all, same issue.
