@MrJamesNguyen I just checked my file size and it is 277 MB, so definitely on the high peak. I haven't had the corruption happening yet, but have also never placed a residential rental, and remove those from Tomarang the moment I bought the EP, out of worry.
Maybe it depends on the computer power how much it can tolerate, or maybe it depends on more than just the size itself. I did a few tests and saw that the amount of Sims in the save have a strong impact on file size. Maybe that's why mine is bigger as I play rotationally since 4 years and have 137 Sims in the My households tab, and probably around 1000 Sims in the "other households".
But I'm defnitely super cautious, checking for any exclamation marks regularly and staying away from residential rentals out of fear triggering the issue ☹️
I'm also always saving in live mode, doing regular repairs, and keeping my mods updated (I use quite a lot of them, which could also be a reason for the high file size, although i don't use any build/buy CC).
