Same deal here. I have moved a harvester around, and a fighter to all my bases, they all have workshops, power plants, large ufo hangers Satisfying every condition I can find, but I cant research UFO theory, doesn't even list. UFOs will NOT go into hangers even when the mission report states it is going to a specific base to be disassembled. Am I missing something or why do no alien ships go into hangers? Is there some pre-requisite that has to be completed BEFORE you can load a hanger?
Why?
Frustrating problem for many days now.
