Thanks for replying, Senka! I have reinstalled the mod and still am not getting any triggers for Imoen. I didn't see the ring in that room at all. I'll keep poking around the dungeon just to make sure, though.
This is my log (I do have other mods installed that aren't listed, such as the banter and flirt packs, and they seem to work fine):
