Hi Lava, thanks for the prompt reply, and my apologies for posting my first inquiry on an unrelated thread.
I'm not sure why the "YOSHIMOISDOOMED" variable was set in that run through, because I thought that I had brought his heart to the Ilmater temple in Waukeen's Promenade, with the comment that "he was a friend who was forced into treachery".
More importantly, I was able to get your Yoshimo's Remorse mod to (hopefully) run from the completion of the first reckoning by deleting the "YOSHIMOISDOOMED" variable, then adding "YYSTART" set to 2, and spawning YYAVA.cre with the console, which spawned YYOSHIMO.cre and initialized "YYINFLU", "YYOSHIMOINFUENCE", "YYOSHIMOREMORSEACTIVE", "YYTALKS", and "YYTIME", after the initial conversation. Everything seems to be running OK (and my PC can stay married to Saerileth and father a big family of untainted grandchildren of Bhaal .
I couldn't download Yvette from SHS because they've been down for months (?). I was able to redownload the mod from Dropbox. I appreciate that your mods consistently allow the player to ask your NPCs to leave during most conversations (albeit rudely), instead of furiously forcing the player to accept them while sugar coating their often extreme personal failings, as Gaider has done with Imoen and Alistair. Ironically, though Aeon is the sort of character I would greatly dislike in real life (for very different reasons, so is Saerileth; Aeon's an over the top male version of Imoen, but without her baggage of acquiring thieving skills by repeatedly stealing from the monks, clerics, and acolytes of the human god of knowledge who raised, taught, nurtured, and protected her [I usually play as a dual class Lorekeeper]), and despite the repeated references to Aeon as "stupid", he's just foolish and impulsive; he comes across as much brighter and more informed (interesting comments about male bonding among humanoid and non humanoid animals) than Imoen (who I could not believe would ever become an accomplished mage, though being head of a local thieves' guild suits her well), and his comments about wanting to become a father were surprising and quite touching (many 'romances' with female NPCs never even touch this subject), I really liked him and the mod (though I cringed when he mocked Zhakee's accent), plus he can be developed into a very effective thief.
Again, thank you!
