Abyss Spawning Endless Monsters

I had two abyss apparently end right next to each other on a City Square map and now one won't close and spawns the same endless 4-5 monsters. The monsters don't drop anything or give any exp thankfully.

I reproduced it, again no exp or drops from these monsters, just endless spawns. Seems to happen when when two Abyss get close to each other near a wall.

I was hunting one last Abyssal Depth for the achievement and got it this map early on, and then decided to finish the map. Then this happened.

Has been this way for many, many leagues and reported dozens if not hundreds of times by now. Really sucks for Valdo's maps as a lot of the abyss completion ones cannot be completed if one bugs out like this. No fix yet.

Thanks for the info, maybe someday.
