It's a very good game at this alpha stage but I have an annoying problem. I couldn't save my game. The auto save also had a problem. In the debug.err file, I found these lines:

DebugMessage:  Deleting save game.   Curr. Memory Usage: 1351553024 bytes
Debug Message:  Attempting to allocate memory of size: 53477376 bytes
Debug Message:  Allocation successful
Debug Message:  Game Saved.
DebugMessage:  Error writing save data to file D:\Users\Jean-Rémy\Documents\My Games\GalCiv3\Saves\\~save1.GC3Sav.
DebugMessage:  Deleting save game.   Curr. Memory Usage: 1408122880 bytes

and the auto save:

DebugMessage:  About to auto save.  Memory: 1419354112 bytes
DebugMessage:  Deleting save game.   Curr. Memory Usage: 1419354112 bytes
Debug Message:  Game Saved.
DebugMessage:  Error writing save data to file D:\Users\Jean-Rémy\Documents\My Games\GalCiv3\Saves\\~Auto Save.GC3Sav.
DebugMessage:  Deleting save game.   Curr. Memory Usage: 1419788288 bytes

Why is there a "\\" ? If I try to create the file with notepad, i can only open it if the path has only one backslash. I wiped the prefs and redownloaded the game but it didn't change anything.
