Sims 4 Reaper making out

My experiment with the NPC Reaper continues!  And continues to yield no results!  I was asked to post pictures, soooooo hereyago.

It bothered me that my Reaper husband and wife - Grim and Hel - never properly made out or woohooed ever, despite having kids I altered from other Reapers (and one made in CAS).  Didn't get them to do it.  Geez, why the Hell not, guys?  I cheated your meter full.  For some reason I have WAY better luck in public places.  Well, I got Grim a little play annnnnnd ... was totally unable to make him a legit Grim Reaper again.

You see, when you place a reaper into your household, no mater what changes you make, he has the hidden trait of "isGrimReaper".  It can be removed and re-added ... unless.  Unless you ... kiss someone.  Or if I tried to add another NPC trait like "isRepair".  Whne I add that it prevented the Reaper to ever become a true Reaper again. 

Which defeats the point.  Sure there's a custom trait, but I don't want a false Reaper.  I want him to have the legit trait.  With everything else being different!
