Ritual, Hive, Delirium bugs

Delirium:
I noticed I never find any "fractured mirrors". Only the first mirror when you spawn into the map. Possibly making delirium rewards much weaker as a result and there is perks on atlas tree that even mentions fractured mirror spawn increase. That's only reason I even got reminded of this that fractured mirrors were a thing in 0.1 (at least I think, it was long time ago).

When you use waystone and infuse it with emotions and then run Delirium map. Even the first mirror fails to spawn. You then can't start and complete delirium side objective.

Ritual & Hive:
When map has overrun with Hive on it (that feature where they are basically everywhere). The Ritual fails to spawn. This happened to me with both Hive as a feature on map and with waystone that I desecrated and found modifier that made map overrun with hive. Delirium/Breach works. Expedition I didn't have chance to test.

Something I just realised with upcoming 0.31 patch that removes towers:
Hive doesn't have precursor tablets, but is unique feature on some maps. This feature should still stay on campaign. I post this solely because in video footage we saw I didn't notice any on the map.

These issues seems quite severe to me. Nobody else noticed?
