Sims Stuck On Edge Of Lot

When playing with dine out and operating an owned restaurant the customers and employees get stuck on the edge of the lot. Reloading the lot, resetting sims, and restarting the game entirely does not fix the problem, and replacing the lot in its entirety also does not seem to help. The restaurant was working fine for a time, but it is now inoperable as no one can get where they need to except for my sim.
