Every so often when I open a saved game, the scenery/footpaths will looks buggy and when I try to add a footpath, the game crashes. It happens on very edited games and no edited games at all. Does anyone know what causes this? My game is up to date also.

(i am new to this game, so give me some crutch) I have created a scenario and something is wrong with people exiting. They cant enter but when they try to exit its like a brick wall. I am very confused and if anyone can help me with my problem, ill appreciate it.
