When coming out of CAS in Live Mode, a different Sim is selected than the Sim that entered CAS. This will switch households if a Sim is receiving a custom tattoo in Hobbies & Skills from the Sim givi...
Ideas
I went to a tattoo shop with my sim and asked for a custom tattoo to the shop owner.
After selecting the tattoo in the CAS, My game go back in the tattoo shop but my sim wasn't on the terrain. In the HUD she's displayed just like if I was at home but she was at the tattoo shop. I can't do anything with her.
Going in the world view and selecting my sim again, fixed the issue
I'm not using any CC or mods
Also the issue is not exactly the same since my sim is alone in his family but I guess if it's a similar bug
I don't have any Last Exception file in my documents folder
