At first I thought it was just a bug with Risen Wizards, but when I took him to do Canach dungeon, he got stuck after getting knocked back there as well.
I don’t know if it just affects warrior, but it doesn’t happen on my Ranger.
I have to use some sort of leap or launch skill to get myself unstuck.
