I recieved the building called Harmony of the Heart from a quest. The problem is it doesn't mark what the game effect is on the description. What does it do?

Hello Fastaff, 

Harmony of the Heart

+5 Happiness on System per Population type (nb of factions present on the System)

Center of Light and Life

+20 Science on System per Population type (nb of factions present on the System)

Feedback will be added soon in the game.
