@luciusstorm Thanks for understanding. I don't think anybody's looks would change to drastically, mostly new accessories and makeup, and one or two outfits. Lucky for me they haven't been on camera with many different looks so I don't have to salvage all of their outfits, just a couple each some of which were already backed up when I went from alpha to maxis match.
@GalacticGal I didn't backup the main save unfortunately but I do have two side saves for times like the proposal where I needed to go back and recreate scenes that happened off camera. They aren't as up to date as the main save, but I haven't accessed them since last weekend either. The problem here I think really was the old cc, the pack and the update were just the final straw. This was going to happen sooner or later as old as some of these files are. I've researched some of them on TSR and they go back to 2014! Some of the creators add things like brackets around their name in the file name which I learned recently also causes issues. It's no wonder my game acts as weird and wonky as it does. I see it as a blessing in disguise. Sure I'd rather be playing with the new pack right now but I dodged a bullet that could have ruined everything.
