Hi, I have a problem, and it's that the green belts aren't showing up in the technology tree. I've gotten up to the blue ones, but researching the green belts ones doesn't appear. How can I get them, or do you have to do something different?

thanks for the help.

You probably search for the wrong word. The green belts are not called Logistics 4 or something like that. Click on the blue belts, then look at the right side (technology tree) and search for the green belts.
