Error Code: 0

I just built a small house in the Sims 4 and was just about to save the game and then quit, when the error message popped up. I tried to search on the internet what the problem could be but i found nothing helpful. I saw something about deleting cache files and moving sims files to the desktop but i dont have any cache files under ''cache'' and it does'nt work to move the save files. What should i do?
