When I mod the Gostek graphics I noticed that when I play Soldat to test them, the arm (reka.bmp) stretches when I look up or down, and a lot when I throw grenades directly up. I didn't change the size of reka.bmp and I even replaced it with the original graphic and it still stretches. This also happened on my other computer before I had this one so I know it isn't my computer. What can I do to fix this?
