Whenever I change the file that represents a map, it always freezes my game. I used GIMP to edit and the images and convert them to a PNG of the corresponding size to the image, so I'm not exactly sure what the problem is because I use the same method to change CSP's all the time. What could be causing this? Does the file need the exact same name? Does the common3_en.pac in my system folder have anything to do with it?
