Fracturing mirrors do not appear in delirium maps

Fracturing mirrors (the ones that you walk into and it spawns extra delirium enemies) do not appear in delirium maps, even without the map being instilled.

The atlas passive which "spawns more fracturing mirrors" of course is doing nothing because of this, but I have tested with it and without it.

Same problem here. I feel a lot of loot is missed :(
