Problem:
As in the new release of A27, the farmstead farming tech upgrade time costs are 40s, 50s and 60s respectively. However, for Han they become 50s, 60s and 70s respectively. This is a disadvantage for Han.
Cause:
In early revisions of A26, the bonuses for farming tech in Han was +25% (in contrast with +20% for other civs), justifying the extra time cost. However, the bonuses were later standardized to +20%. Consequently, the extra time cost becomes redundant.
