File won't save when I click the X pygame

In my code pasted below, I try to save the new level status(what level the player is on) in stats.txt. When I read the text file after saving it in the code, the file has the correct value. But when I click the x to close the program, the file reverts back to before I ran it. If I force close the program with an error or if I close the program while I am in the level I unlocked, the file saves properly. What do I do?
