I cleared his traits by eating the moonflower petal. only way to do it I know of. my next thought was to cure him completely before rebirth. he had also died twice and did have his urn at his home when he went to rebirth. I read somewhere you might have to take it with you. even though it says they like to visit them after re birth. as far as traits goes he has a very high amount to figure out if it is a trait would take me weeks. almost all aspirations complete and traits bought so on and so fourth. Were wolf infants have always had difficulties especially so with the greater and he was one of those. greater infants can be saved by themselves but it tells you it's an invalid household and best to be deleted. how ever after you add it to another household it's fine. so the issue for me could simple be him being a were wolf. plus if they die more then once before they rebirth it causes another issue as well. I don't really know what it could be for my sim. but the ones this tag was for is probably because of multiple deaths. I really have no further guesses about what is wrong or what i can try. I'm fine with him sliding into in active and working with him from there but it's just not as advertised.
