One of my planets won't finish the item in its military construction queue. This started after I'd purchased a Constructor at it, and then realized that I'd just researched Impulse Drives, and so I changed the item in the queue to the new type of constructor, whcih cost ~5 bc more. It said it would be done the next turn. But it wasn't.
It's sat at "0 Turns" to completion for quite a while now, and never gets anything done. Interestingly, it displays "0 Turns" for any ship I tell it to build, even ones that cost much more than the constructor I told it to buy. I had it build nothing for a couple turns to see if that would clear it up, but no. It still displays "0 turns" for anything I tell it to build. I've saved and quit and reloaded, and it's still messed up. This is kind of annoying, since it's a medium map, so I don't have all that many planets and I'd like for this one to be able to build ships.
Has this happened to anyone else? Is there a solution? If you're Stardock (or, more likely, just happen to work for them), who should I send my saved game (which I presume you'd like) to?
