This isn't a TA bug per say, but I figured it might deserve some attention in here.
The food distribution center increases food production by 25%. Yet, at the same time, due to the way the happiness rules work, having more than one or two farms -- three, at most! -- just isn't something someone is going to do by the time they get this tech. It would be useful early on when the first farms are released, but once you get to the third level of farms -- required for the building -- its useless. A second farm would double your output, not increase it by 1/4, and even that is generally too much unless you have a lot of +morale.
Anyone else thinks that building needs to be looked at? (Or have I missed a use for it?)
