Whenever I collect an UFO, I have an option to either sell it, or (provided I have an UFO yard), store it there. Now, the problem. I can't for whatever reason, be that lack of free space (if I wanna store an UFO type I don't have yet, but have the yard full, or just wanna intact one instead of a damaged), or cash shortage, sell those I have stored. Nor, actually, get a list of what I have there.
