I started playing with united kingdom 1936 campaing, at october 1939 i started to use my navies, so every time when i click on certain ship type in fleet (like HMS King George) the game crashes, this happens when i click on every type of ships exept carriers or subs. Then i started new UK 1936 campaing just for test and no crash. Could my save been corrupted? I started that crash game with 1.3 patch.
