I don't know what caused it, but my savegame now give an error message:
I guess I lost my savegame, but why it happened? Any idea?
I tried testing with r3872 but, the .exe from nightly page download crash when it finish loading, and my compile crash when I try to load a save.
Here's my save (http://simutrans-germany.com/files/upload/pak96.sve) if you wanna take a look.
The game was not saved completely, a lot is missing. Either harddisk was full or simutrans crashed during saving or write error in OS.
Thanks for quick reply.
Now I can see how important autosave is. ;D
