I've been playing a base named "Crashpad" for the last couple of days. Today I was generating new games and not really paying any attention to the name of the base. One of the new maps created auto-named the base Crashpad and overwrote my current game save! Ugh... Thank god for those auto-backups is all I can say. The game engine shouldn't overwrite save files when generating a new map.
Name a base, play it, start a new game and give the base the same name.
