Hey guys! So I have a sim family in University and I wanted to add one of my sims girlfriends into the household but whenever I try to through Master Controller on the computer, it freezes my game and then crashes it. Is there any fix for this?

Well, that of course shouldn't be happening but without more information to go on it might be difficult to figure out why.

May I ask if you have the usual mods in play in addition to MC to protect against common errors in these situations? Namely ErrorTrap, Overwatch, Traveler? Might ErrorTrap in particular be kicking up any script error logs that we should be reading?

Is there anything special about the sim you are trying to add or is she just a typical Uni student or resident of Uni World?
