Yogi... click on "WORKSHOP", then select "NEW" button, and select "Colonizer" from the CLASS option. Click OK and the Colonizer will be back.

Thanks Joseph. I think in figuring out stuff and tinkering with things that I probably deleted the Colonizer. I recreated it and all is ok.

Am I crazy or what? I don't see a selection to build a Colonizer. Do I need to research something first? I'm 4 years into the game and need to expand.
