Short intro: in act 3 while fighting the Lohse Demon - Adranahlik(or something similar), after the fight start he changes forms from human to demonic. This makes his human form disappear, which PASSES the turn to a PC or NPC that was second in line.

BUG: After the Adran reappears in his demonic form he cancels your PCs turn. So that means that you character with the highest initative is stripped of his/her turn untill the next round where they are places as they should be AFTER the demon.

This is very similar to the situation with Hannag fight in Act 2 where she spawn portals and portals spawn Voidwoken. In this fight if you destroy portal while still having some AP left, new portal will appear and from it Voidwoken will spawn gaining a turn IMMEDIATELY canceling the rest of your turn.

I really hope this is a bug not a feature and you guys will be able to fix it.
