Did you start a new scenario or are you continuing a previous one? If you continued an old save, you will have to start over. I just verified in-game, that the missing production yield is fixed in 1.32, but the fix can't get applied retroactively to an existing save-game.
Still, you could also use rush-buy to get all the improvements you need. Research Civics to get the ability to rush production, and wait until you have enough Gildar. This will take some time, but it should work.
