@crinrict Mainly base-game traits, but the mod ones I'm using have never had this effect before, and I've used them for at least a year at this point without trouble. I also had a look at his hidden traits but found nothing out of the ordinary or anything that could be the reason for this happening.
I created him myself. I have a clean save of him in my gallery, and have pasted it many times without this problem, so it seems to be this particular paste of him. But this switch started happening only maybe a month ago (real-life time). Back when he used to live with his family and also at university he didn't have this problem.
