Im sorry i don't know what you mean "delete the first line", but anyway I did what you suggested about lot traits and it didn't solve anything but i found out that i have an issue with one specific sim. Like i said before, I deleted all the mods so I don't know whats wrong with him.
I couldn't attach the file so im pasting it here
