I have been having similar experiences, first with Novalith cannons that would not fire, then with fleets that would not accept specific attack orders (even though individual ships could still be ordered one at a time). Now, I can't build anything...the computer appears to be logging the build orders, but nothing is happening. I had gotten through quite a few games successfully, then installed an update and now, 18 hours into this game, in the middle of a very complicated multi-front campaign, the game engine develops this glitch which basically renders the game uplayable. If this is a known bug and there is a patch, I'd like to know about it...
