Sorry, can't take a video atm, but have some leads!
- Don't think she's even meant to have this spell, right?
- She casts it over and over on party members and herself, probably because of its short duration
- She had boots equipped that gave her Flight of Foot as a worn effect. I swapped them out in case that was related.
- Removed all mods and restarted game, still happening.
- Swapped all her gear out for basic gear, still happening.
- Invited another same lvl druid to party, they didn't do it
- Kick Cyndara from party, she stays there continuing to cast it on herself
- Eventually I remember you added something to let sims cast spells that are activatable effects on items even if they don't have them equipped, like players do
- I discarded the boots with the Flgiht of Foot bonus and also an Aether's Blessing she had in her inventory
- No change
- Restart game after discarding those: she stopped!
So I'm wondering if it's mistakenly letting her cast spells that should actually be worn effects, if they're present on non-equipped items in sim inventory. Hope the details help.
