Thanks, Vorm. But, well, crap. The reason I crafted the small metal one was so I could store it in my mobile base and travel with it when it isn’t being used. I was assuming the stone one was a permanent, fixed structure you can’t pack away so I didn’t build it. I don’t want to have to build a new one every time I stop someplace new.
How on earth do they expect you to figure out how to use the smaller one, anyway? That’s horrible as far as UI goes. That makes me strongly suspect that this is a code hack and obtuse because it was the only way they could figure out how to get a smaller one to work using the current game’s code structures.
