I am having this issue as well. I have no mods, or CC. I just got eco lifestyle and just recently started playing university. I dont know if it's the new pack hearing it's as glitchy as is. My sim will stall if I request an action and sometimes cancel it to do whatever. I tried clearing out the cache, and repaired it. I already had to uninstall it once due to a bug in eco lifestyle. I'm not entirely sure what to do other than uninstall it since I've been having multiple issues with Eco lifestyle.
@lizandnick6410, you could try a factory reset of the game folder and then try repairing your game through Origin.
