I think I ran into the item limit problem in the worst way. I defeated a battleship on the ground and took the commander. Then I was all excited to use the 200 elerium I should get, but I received none. Is this because I am playing on superhuman, and the number of alien corpses overloaded the overall item count? If so, I will be sure to destroy some items next time before finishing the map.
Note that I did not use any explosives near the battleship.
