Is it possible to decomission a manufacturing or tech capital improvement? In my current game I took one of the acrean's planets, a class 7 that they managed to snag deep inside my territory. I find out they built their manufacturing capitol there and to boot it was on a tile with precurser mine for research!!!! I would sure like to use that bonus but I dont see any way of turfing that manufacturing capitol, of which I have two now, how does that work?
