Sorry, i didn't mean "nice" as an insult, just a word, i also could have said good. It did imply that players could somewhat control it though, by keeping their save file small.
This of course, does happens in long played saves with or without r-rentals, but that's not what this thread is about. r-rentals are directly corrupting the game, whether it is played or not, and no matter how long. If your save corruption is not caused by r-rentals, then you're not in the right thread. This one is specifically for problems caused by r-rentals.
Again, i'm not saying your problem isn't just as bad, but this isn't the right thread.
faithvssamMy corrupted save is big AND has a lot r-rentals, too. Approximately 50 units spread across all worlds. But now, my backed up save file in which I have not saved before the corruption starts and in which I reduced the rental-units to about 25, works again without any problems.
