Greetings!
A new patch is available for the Space Food Empires mod. It updates the mod to version 0.21 while adding a new dimension to the mod with facility pollution and worker unhappiness, while making lots of little fixes and changes. It's savegame compatible with existing 0.20 games. Just download and un-zip the patch to your Space Food Empires mod directory.

Note you'll need to download version 0.20 if you haven't done so already in order to apply the patch!
Unfortunately those AI tweaks and improvements will have to wait for the next patch which I'm hoping to have ready in two weeks.
Also, the mod has a dedicated forum for discussion hosted at Spaceempires.net:
