I figured out how you have to select which area to develop at the start of the game, so I found the sites in the woods. And the orc. Not sure how all this will go.
Will development of the other buildings ever proceed? I see no way to progress with them. Maybe a future update. Or maybe multiple playthroughs, developing each one from the start.
(nvm... I finally found the menu for upgrades. I missed SO much.)
