In one of my towns, all the sims are having their personal inventory items moved to the family inventory in build/buy mode. I found this out by trying to get sims to join jam sessions with sims I know to have instruments and can play. Also I noticed they were not driving their regular vehicles. Suddenly none of them have the option to jam. So I checked with several houses of the sims I have built up only to find absolutely everything in the family inventory. They were either using taxi's or sloppy jalopy's and had no other items. All their food, collection helpers musical instruments, vehicles, everything. I went through the process of taking everything out of the family inventory (placing on the yard) and putting it back into the personal inventory, except for food. Too many items to move individually. Then I evicted them and put them back. Went the grocery store and got them new food. Did a save after every house. Took me a couple hours. I think this has helped. However, the townies I don't control and who I often ask to join jam sessions, also cannot join in. So I know the same is true of them and I suspect the whole town. Does anyone know what has happened and how to fix this?
