I managed to start to get this to work on a new game but while doing the Nyon quests a new Grim Reaper spawned and my parent Grim Reaper is now stuck in relationship panel cannot invite or spawn, nor available in not in world households. I was using the traits.remove_trait isgrimreaper and then traits.equip_trait isgrimreaper method but this may be a pre-L&D method and I do not use MCCC, just cheats. But he lost his job as in the reaper career (and I think when I readded it it removed him as the Grim Reaper).
Does anyone have a way to add the Grim Reaper as a parent without glitching breaking? I basically add Nyon and my main (to be half-siblings).
