[FR] Corrupted Lots/Houses disappear in saves with lots of rental units

I've had this issue in a save with many rentals, but not an extreme number (around 50 units I think). At a certain point, loading any lot, I had the wrong lots showing (the default ones instead of the ones I built). 

I had this happen to a save after For Rent came out.  I could not enter many regular residential lots in Willow Creek, making that particular save unplayable and unfixable.  The fact that this is still ongoing is unacceptable.  This is a game corrupting bug and is barely talked about.  The only solution I have seen anywhere is to not use rental lots in the game.  This is not a solution given that people have paid for that gameplay.  I have had to start a new save file and am not currently using rental lots.  This needs to be fixed ASAP before EA sells more packs to unsuspecting people who just want to play a game.
