I'm not sure if this is a case unique to me, but several times today while doing T1 stuff, my movement keys have acted as if stuck, so i'll continue to go up, down or left or right. while it can be fixed by pressing the key stuck a few times, this is a very annoying bug.
This also happened while at the auction house once, where the e got stuck and there were suddenly almost a 100 e's having to be deleted before i could write something again.
it seems to be related to the amount of stuff surrounding my character, the more enemies+allies+other stuff, the more likely it is to happen that keys get stuck.
I have sent several ingame reports and talked to Cronus via support email, however I have yet to see any solution to the problem
