I dont know if anyone else has this problem but sometimes in the campain when i have my soldier lying down and i try to crawl forward my guy will fly up into a standing position but his arms will be pointed out to each side so that he is in a t shape. i can then move him around but his legs dont move he kinda just glides around but then when i try to shoot he goes back to a lying position and shoots instantly. it is very strang
