[Bug 3.878.494.557] Infinite Abyss Crater

Hello,

I was doing an abyss on a Castle Ruin map and at some point it transformed into a stygian spire near the bridge before the boss area. I destroyed the stygian spire, but before it got destroyed it created one final crater and to get to the point i've been on this map for like 10 extra minutes killing abyss monsters that keep appearing from that one crater. They don't drop nothing and don't give xp they just keep spawning.
