Actually, I have one and posted my bug story on EA Sims site. A helper told me it could be from mods/ccs with the bug. Another simmer posted his or her vamp sim is abducted and now pregged. I'm looking forward that simmer's story.
He had the alien ring with vampire needs bar after aging up to teen.
He had a strange thirst moodlet for 1 day.After moodlet's gone, his plumbob ring is turned into vampire one without any specific animation.
His birth certificate
My bug is that I can't change his hairs and clothes.
I can change them in CAS, but he just gets back to previous clothes after that in live mode. I tried to change it again after removing mods folder and repaired game but the issue is still going on.
I'm not sure this bug could be from cc/mods, that's why I wanted to know there is other simmer playing without cc/mods would have my case. I'd like to know my sim is glitched from corrupted save file or not. Even I don't know this vampiric Alien is normal or Bugged occult.
