Worked the day at restoring my Sims 4 game...
it seems to be "functional" .. a few "glitches" and a couple of other issues (but we can work around those) ..Had to delete the few Zombies (non-compatible) but, got to keep most Mods ... All of which had to be re-installed (the creator of these "violent" Mods ... "Sacrificial", quickly posted a matching set of them for the update of Origin)
Thinking of trying this one in my game... will try the "become Possessed by the child"... should be Fun... got "immortality" for three more Sims.... this Mod could Kill them otherwise....
