Just an FYI but I've noticed a very minor bug when playing as the new Lothlórien faction (which is awesome by the way - really fantastic work!). If I get the 'Marchwarden' upgrade for the fortress, when it completes I get the sound-effect and on-screen message for 'Upgrade - Silverthorn Arrows' and none of the Marchwarden units appear on the roof. It's only a very minor thing and doesn't affect the game play at all but I though I'd let you know just in case!
Keep up the great work! Can't wait to see what comes next!
