@SuzyCue72 My playstyle? I use all expansions I have at the same time. I also tend to play social people who know the whole town after a short while. The game then started forgetting portraits. Going to vacation world or university didn't help, because the list got even longer. Then the game started mixing up who is where, one of my Twinbrook guy's kids ended up as a homeless toddler in China (I didn't even know the kid existed, I only found him in the family tree), and every trip left my guy going naked to work, or worse, in some broken outfit that produced weird sprites on the screen, breaking stuff in the house, deleting my sims' vehicles, etc. Lets not talk about the game breaking completely when it bloated my savegame with useless pics.
Anyway, most of those issues went away after I started using NRAAS mods. They don't catch all the nonsense, but most of it, which is fine by me. And no, those leftover social jigs don't happen that often in my game, either (I've seen maybe 4 so far). However, the first one appeared in my Twinbrook game, without mods. I had to find out how to get rid of these, and the mod versions of resets tend to be less intrusive than the vanilla workarounds. This was especially important for university, where the game usually broke sometime during week 2. If you reset your sims, they will lose all academic progress, which is annoying. And yes, it happened both times I went there the vanilla way.
