Nightmare Dungeon can't be done

Now I have had it several times that it wasn’t possible to go through the dongeon. The mission is to kill all the enemys but there is the last enemy behind the closed door, you can’t kill him because the door is locked and only openable after killing the last enemy.
I’ve ssen in rhe Bug Report list that this isn’t a new bug (last entry Jun 20). But I think after now 4 Month maybe you are able to fix it. To have it one time it’s maybe okay, but several times that’s not so funny.

I just had this happen to me in Luban’s Rest. One monster left to slay in order to open the door and the monster is hiding behind the door. sigh
