Cursed Bite?

So... I was playing and to complete my sim's aspiration, he has to bite 3 people. However, every time I tell him to bite someone he turns into a werewolf, and then gives up on the action. I've already uninstalled the game and installed it again. I set the game to repair and cleared the cache (I did this before uninstalling). But nothing worked. I thought it was something about not being able to bite sims who aren't your friends. But I did the test and asked if the sim wanted to turn into a werewolf and this random sim said yes, so when I told my sim to give the cursed bite again, he gave up. I've already used the reset object cheat (both on my sim and on the other one) but nothing worked. I don't know what to do ;-; HELP!
