I don't think it's Isra, since she doesn't alter that last dialog with Prism. Is Greywolf definitely dead? You might be able to set C:SetGlobal("GreywolfCharmed","AR5400",1) manually to trigger that dialog, but doing a new load order might just cause more problems.

 

(Also, thank you for the heads up, nullset! I'll fix it eventually.)

I'm getting the exact same error that DrBob did. Killed Greywolf (after several attempts >_<), only for no conversation to initialize. When I try to talk to Isra I just get a "I'm afraid I'm rather busy at the moment" line and Prisim just chants that soon his work will be done. I'm running a few others mods, but not very many: Modmerge, Valarie, Eldrich Magic, Unfinished Business, and Quests and Encounters.
