[douglas]

Without police troops, UPC's, substantial military presence, etc., and without anything significant happening, happiness gradually changes towards indifferent. Since colonies start out at happy and the initial colonization rush gives empire-wide happiness boosts, most of his planets have likely been at happy or jubilant for a while but are now sliding back to indifferent. To prevent this from happening, build a few troops on every planet.
