Don't know if I'm being stupid but after 3 of my 5 units were defeated, I can't seem to get them on the board. If you have to resupply them than I have no idea since none of the walkthroughs even mention the strategy portion of the game and the tutorial flat out doesn't even mention it. Also for some reason, in some battles, my two units can only move to certain tiles even if they could normally. This especially prevelent in Lind's battle in the academy where I can't move forward at all down the red carpet. I can only go to the right or left towards the book cases near the entrance.
