I love Max; but, he wanted to become a vampire and after my sim graciously granted him his wish, my game started getting glitches. I haven't had to resetsims for the longest time; but, when Max became a vampire, I had to reset constantly. My plan was to turn Bridgeport into a city of vampires with Max and Cheri as the founding parents. Cheri, a longtime vampire, already owned half the city before meeting Max.
I'm using no mods and the game housing.
