Issue
The save game starts to disintegrate itself. Lots start to get deleted, causing endless loading, loading into empty lots.
This happens to save games that have lots of R-rental units in all ...
Ideas
I started a save file by downloading off the gallery. Some had rental units and I had to restart as some lots would crash or have endless loading. And, then the save started to delete lots. after restarting and using some new lots it was better, but now it is starting to corrupt again.
