[12.10] MP Dedicated Server not saving game

[ibsteveog]

I run a 12.10 dedicated server (on windows 10) and when I shut down and restart the server, nothing has been saved. I have to go dig up an autosave to recover the server.

My startup file (start_dedicated_server.bat):
@Factorio.exe --start-server 2015_OCT_09_current.zip
@pause

I switch to the console and press Ctrl+C to shutdown the server and like 10 hours of playtime and the game is never saved back into "2015_OCT_09_current.zip".

For every relaunch, I have to manually go to the saves folder and move an _autosaveX.zip file over to that name (the 2015_OCT_09_current.zip) to pick up where we left off.

What am I doing wrong?

Right now, the best workaround is that I save the game on my client, and then copy that file over to the server the next time we launch so that there's no 1-2 minute rollback.
