My Game Keeps Crashing, Still! (A Slight Rant) UPDATE!

UPDATE: I uninstalled via Origin, after making a backup copy of my Sims4 game folder, just in case. I have excellent news! I was able to place lots from the My Library and when I scrolled through all of my saved households, I didn't spy a single red/white Sim among them, when they were peppered throughout my saved Sims! I played for only a couple of minutes but so far all is well again. YAY and thank you so much, ALL of you who offered suggestions and your support. :)
