My issue is simple, i can't find the "maps" folder that should be inside the /base folder, i installed the game from GOG, as i did before, and most of the time it works pretty well, but now, the folder simply isn't there. I want to open some of the multiplayer maps on SP for fun, but without the maps folder, the game doesn't find them, it's singleplayer campaign seems to be working fine btw.
