I encountered Moria Summer in the Swamp Biome. After defeating this boss, my reward included using Mora's heart on a city and give trained troops there a special trait to boost consitution. However after selecting a city, that city did not display any additional trained troop bonuses and new units from there did not get the special trait. Is this a bug?

Also, after clearing out all the lairs from the swamp it did not revert to settle-able lands. Is this because i killed Moria? I was able to revert the swamps to normal lands once before encountering moria.

Altar have this special trait that allows training of Henchmen units. But when creating a custom race i could not find this trait anywhere. Is it for prebuilt races only?
