I can buy the robot crafting station, my sims want to make robots... can't click on it with the sim, won't give me any options for it.

At home, university dorms/houses, or even on vacation; my Sims can't go anywhere. They call a cab or try to book a tour; 90% of the time they either instantly get out or come back, or the vehicle leaves without them and infinitely loops, or something of that nature. If I have boolprop testingcheatsenabled on, it gives me multiple errors at a time, and if I chose "cancel" it just keeps giving me the exact same message ((I read it down to the last digit/letter)); "reset" ends up with it being like I hadn't called the cab or booked the tour or such; "delete" ends up deleting my Sims!!!

Please, help me!!!
