Azmeri Spirits not added to map

I'm unsure if this is limited to abyssal overrun//unforeseen consequences maps, others' experiences or relevant discussion; what I've experienced is:

1) allocate drawn to the light (powerful map bosses have spirits)
2) use overseer tablet to empower map boss
3) also have area is inhabited by add'l spirit on a tablet
4) check map mods, says area has 2 spirits
5) run around entire map, find no spirits.

I do sometimes find spirits and I'm unsure if they are due to atlas passives/random encounters, and generally feel like "area has x% increased chance to have azmeri spirits" modifier works, but I'm not going to isolate that for testing.

I also have unstable energies (25% more effect of prefix or suffix on maps) and all the tablet effect nodes allocated, so maybe there's something weird going on with rounding?? Does, e.g., 2.5 spirits = 0 somehow?

I also have some weird theory that spirits get bricked less often with rituals on the map, but no real basis for it, just tinfoil hat stuff.

Anywho, hope this helps. GL HF click buttons!

edit: spawns by map yes/no
cenotes - no (with unforeseen consequences tablet, dropping that unless indicated)
