Not quite sure it's related, but I've been having wonky targeting issues yesterday and today on my warrior and assassin. I'd C+Space to get to the nearest target, and for some reason, I'm running nearly half a map away from the nearest target. It also seems that my warrior is running around minions and heroes, almost like being body blocked. It was most noticeable when I was doing the quest to gain Olias on my sin this morn.
I targeted Erulai at the bloodstone, and my entire team ran past him, up the mountain and got stuck.
