Asala not following

In the Halani Gates you need Asala to open the gate mechanisms for you. For me she stood still after killing the rare impaler monster and won't move anymore. Reloading and summoning her again helped, but she stucked in impaler fight again. I finally managed to continue after reloading the instance again and avoiding the impaler fight.

Just had the same bug. I fought against the rare mob at the forward command tents and now she doesn't follow me to the second gate anymore.
