I had argued in another thread that they were working but I was mistaken, I must have gotten a manufacturing bonus at the same time when I had checked earlier because I've been paying attention to it this game and none of the bonuses are working now. The cost to rush build stays at 1515 for the full cost and I just completed a +10% synthetic growth tech and the time to build and costs stayed the same. Please take a look at this and resolve the issue.
