It has been happening to me since around Morrowind update. I will be running forwards and rolldodge, but my character will go backwards. This has gotten me killed lots in battlegrounds. For example i will be running the relic with the enemy team chasing me down, I will rolldodge as I'm running forwards to try avoid some damage, but instead of rolldodging the direction I am running my character will rolldodge backwards towards the enemy killing me. Result = me dead.
