I can't seem to be able to select my character, in order to move him to the mission I need to do, in order to progress further. I'm Stuck at the castle to liberate from Marrok. I keep ending my turn, in hope of it letting me select my character.... my troops have leveled up, but I can't select my character to be able to use that option. I did do some Diplomacy stuff, where I did some trades, and sent some troops as escorts, is that why I can't move?
