Infinite abyss spawn + can't enter abyssal depths

example video and has map mods at end (may have to pause) but another abyss in the map spawned infinite mobs without spawning the spire from the abyss scarab of edifice as well as the abyssal depths in the clip spawning infinite mobs and not being able to enter. Just speculation but I've only had this happen while using the edifice scarab, never in any of my previous abyss maps.
