I went to place a lot yesterday and my entire savefile suddenly corrupted. I realized it was corrupted because after I placed any lot, all of the other lots in my game reset to the original version of them. They all looked fine from world mode, but once loaded into any lot the issue persisted. Read more about these issue here.
I rolled back the save and it was fine so I decided to try and remove the entire pack and see what would happen. After removing the pack, I could place new lots and the game was fine. Which meant for me the issue is FOR RENT.
I was nowhere near the limit of residential rental lot nor did I use any cheats to have more than six units per lot. I was not placing a residential lot when it corrupted. So far it seems fine to add the pack back and just avoid the lot type.
TLDR: Removing FOR RENT prevented my savefile from corrupting when placing new lots. The steps I used to stabilize my savefile are below.
Hope this helps!
Steps to remove For Rent:
1. Use this to load the game without For Rent. 2. Follow this if you end up with two different Tomarang Worlds when you load the pack back into the game. I did. 3. Remove each residential rental lot. I set them all to residentials. 4. Replace all of your household outfits that got messed up. Otherwise some sims will be nakie.
Tips:
Backups: Helps if you have backups of your households and lots in your trayfiles. Fixing outfits: If you don't care about relationships you can delete and replace or use MCCC to copy and paste the outfits back on the sim. Or if you have a dresser file, run that for new outfits.
This has happened to me a few times, but this was the first time I decided to see if I could role back the game, avoid the corruption, and restore my savefile.
