Abyss not closing or moving

Bug Report ID: #224682404

I was running a prominade with 2x abyss of multitudes and 2 x abyss scarab and 1x abyss of ediface when I encountered a merc that I challanged and lost to as the abyss was open.

When coming back to the pam the abyss was frozen in place and continued to spawn small monsters like it was doing it's movement animation. I went away and finished the map boss, but even after coming up it was still in the same position and was closed or not spawning 1-3 monsters at a time.
