How the heck do you rebuild the outpost???????? Please help!!!!

after you plant the 3 trees you can click on the outpost and a picture will pop up and click the picture and it will rebuild itself. hope this helps

I have the same problem.. I did plant the trees and I am clicking everywhere on the outpost but my hero does nothing and no picture pops up either.

Do I need the drill first? Or complete all trade and bounty challenges?
