So I have a male couple in Sims 4, with the spellcaster father able to get pregnant. Now out of the 4 kids they've had so far, all have been Spellcasters too. They all have the Weak Bloodline trait. This was immediately worrying to me because I thought at least one should be a werewolf by now. Now, this is the first time I noticed one of the toddlers having a New Fang Pain moodlet. From everything I've seen online, sims 4 doesn't support hybrid occult sims, so I'm thinking this has to be some kind of mistake. I've had this concern prior to the patch that made them age up drastically, so I don't think this is related.
