Sims 2 Legacy - University Bugs

Hi, just wanted to report a bug I encountered while having a Sim at University. When I had her go to another lot, I was unable to put the game in 2 or 3 speed, it would end up going back to 1 speed. The next 2 lots I visited, the opposite happened and the game would not allow me to choose anything except 3 speed. She went to class from the cafe lot, and then when I had her take a cab home, I got stuck on the loading screen, and had to exit the game :(
