[MOD RELATED] Sims disappeared from household/Blue flashing square on map

I select a household to play with and their icon flashes blue with a loading circle as shown in the picture. I hit the play button and nothing happens. I thought it might be my cc so I took it all out, but I kept having the same issue. I also repaired the game and reset my computer and I’m still having the same issues. I'm very frustrated with the fact that I deleted my whole save file thinking that it’d work and it still doesn’t. I don’t wanna delete my cc too that’s taken me almost a year to collect.
