While playing thru .50 and messing with auto resolving battles, I noticed that in your army list, its always the very bottom unit that gets damaged.  I changed this up between my new npc and my sand golem, and with the sand golem on the bottom, he started taking the damage and not my new npc.  Not sure if this a bug, if this intended or what, but thought id let you know since I found it strange in that all my auto resolves for battle, it always the bottom one that takes the damage...even if its a ranged unit(which my npc was) and should be further from the battle.
