Maybe this has been already reported, but sometimes when I build that orbital death ray with the fancy name, it gets to about 20-30% and then just gets stuck. No matter what I do, it won't build past that. Sometimes it does get stuck, sometimes it doesn't, but it can be pretty annoying when I rely on it and it contributes nothing.
There is known bug with orbital fabbers: PA#2959 If you interrupt them they won't able to continue orbital units, but land/air units still able to continue orbital building.
