Tried about four times to alter a sim and the game just says nope and discards all the changes after I hit the tick. I'm trying anything I can think of to get around this problem. Right now, I can't even find her, she's disappeared off the face of Sim-Earth

EDIT: Found what it is, it's one item in CAS that's faulting. It applies fine in CAS, but doesn't show up in Live mode along with other changes
