Are you supposed to be able to Save+Load a multiplayer (1vAI) game?  I tried this, and after clicking Load:

• It took ~5 minutes for the "Creating World..." bar to go from white to full grey.
• After this, it stayed at full grey for another ~5 minutes, after which I Alt-Tabbed and closed the game.  It had to be closed via the Task Manager because closing the window did nothing.

Notes:

• I did not Alt-Tab during the first 10 minutes (which has been reported to cause loading to hang).
• During these 10 minutes, the looping intro music never hung.
• On the same machine, reloading a single-player save is usually very fast (<10s).

No moves have been made in this saved game.  I had restarted to change some video options.
