I ran into a couple of what I think are bugs.  First, after henchmen has been researched, the Alterian build list doesn't include the Torch Bearer.  Second, I received a random quest where I was approached by squires asking to help free their lord.  The reward for the quest is another hero. I accept the quest and get the squires as a unit.  After I fight the battle, the lord thanks me for freeing him and offers to join.  I accept but there is no hero.  Still having a lot more lockups than FE, but I'm really enjoying the game.
