I have found an issue in game whereby in this example my shipyards sole sponsor (my capital) switches to 100% social production on the gov tab and yet when the shipyard is toggled to repeat build a ship, it will continue to churn said ships out as if it had full military production, in this case 1 ship a turn as my capital had around 300 manufacturing (hammers).
The shipyard in question displays that it isn't receiving any production as it displays turns till complete as a (-1) which is at least different from when it is supplied as then its just a (1). this may not be a bug and if that's the case forgive my lack of insight. however if it is the case that this is a bug that's basically creating free ships, then i thought you'd best know before launch.
I may not be active on the forums but i have played about 69 hours of beta now and i love the way its shaping up, just wanted to add something i hadnt seen on forums reported, thanks for a great game!
