Thanks for the basic steps for testing.🙂 I think I wrote slightly wrong that I've done 1,2,and 3 when I had this issue last winter time. So I thought it could be from sim moving to other simmer's game. Currently, I couldn't test this without mods from losing the previous save but I already had this all test last winter time. If the mods was the problem, then I would have found the broken mod or saved game problem last winter time as I tested this in the sims 4 folder without mods. I didn't need to do 4 and 5, I didn't have any mods problem. I'd like to hear there will be any other simmers have the same issue.
