I just got 3m in aid and was in the proces of buying infrastrucure. I bought 70 infrascructure which made my population hit the 10k mark and then got a factory. Befor i bought the factory cost per infra was $15,634.53. now that i have gotten the factory it wants $17,768.54 per infra. I thought the factory was supose to help bring cost of infra down.
