Okay but how can I do to solve the problem ? I need to know how long it'll take to build !
How can I de-activate the carry-to-military-prod. option ?

Several options could fix this. First, usually it fixes itself if you add more buildings to the production line-up. Second, if you click on the focus production button for social (top of the planet screen) then it will start factoring it in. Then you can readjust to normal by clicking it again, or whatever, as you see fit. Or, if you leave the planet screen, and come back, it also is generally fixed.

And, if your money goes into a negative amount all research and production will stop until it is positive again.

its -500 atleast on masohistic

But again, I think it was better to put on an option to choose if you want to do this automatically... Hope there'll be an option in 1.2... Thanx again!

No it won't, because it'll screw you over otherwise. It's spending money on nothing when you're using social with nothing to build, so don't expect an off switch.

This is a very annoying problem and something that should be on someone's "To Do" list.

But the game updates the social as fast as it can, It needs to see the data to evaluate it correctly. I'm fairly sure it can't do this automatically, and social is (as I said) non-existant at the start.

It isn't, really, though. Have a planet not build anything, and the social production will still be displayed at the top, along with arrows to indicate that it's being diverted to military. However, the fact that it shows the social production means that the game already knows what the social production is, so getting it to use the available social production (which is however much is being shown in the box up top) instead of the current social production (zero) should be possible.
