Encampment building bonuses retroactive? I've tried to find the answer to this question but no one seems to have a definitive answer. Encampment district buildings give XP bonuses to units trained in that city. 

Example: Barracks give +25% combat experience for all melee and ranged Units trained in this city. 

But does this count only for units trained in the city AFTER the building is built? Or if I build a Swordsman and then build a barracks, will the Swordsman still get that XP bonus?
