I my inventor sim made a time machine and he and his wife tried for a baby in the past and got a teen daughter. Later, they tried for a baby in the past agian and got an adult son. For a while he was invisable and on a different lot unable to come home. I used testingcheatsenabled and had him teleport to his parrents house. He got there and I kicked him out. I noticed that time has stopped at 7:24 am. The sims are still doing stuff, but the time will not change. Hitting the speed time up buttons do nothing. I tried moving the family to a new house and it's still 7:24 am. I switched households and still time is 7:24 am! Is there anyway to fix this or will I have to delete the save and start over?
