Unique Trait has been overhauled for balancing reasons.

The original Version 1 unique trait provided +2 Science and +5% Global Unhappiness per every Science building, (Library, University, Public School, and Research Lab,) while the overhauled Version 2 trait instead provides +3 Science and +5% Global Unhappiness per every Military Base and Research Lab. This was done to balance the mod and to keep confine Unhappiness issues to later eras.
