Armala frozen and transportation not starting

Hi, both in act 7 and Sunken City, Armala was frozen (not moving, not attacking) in one corner and couldn't die even if she reached 0 hp. You needed to leave the map (or enter again temple of decay) for the boss to work properly again.

I've done 2/3 syndicate encounters and I'm in front of transportation caravan but it wouldn't start.
