So… I did go all the way through and created the obligatory sim and placed them on a lot. In that time, there was no error showing.
I did get the error after placing my saves and tray folders back to the new sims game, still without mods. And I found out that two of my three saves showing the same error after wanting to load the household. Both of them I played with mods (before, not now, I still have mods out of sims folder) and the third one, which I played all the time without mods is okay…
So maybe I had a broken mod which broke my saves… Is there any solution to a broken save or should I just delete them and start a new save?
Thank you for your help
