Just played the Caporetto scenario using 105a and noticed something odd: there are air units in the reserves of several of the armies? The problem seems to be that one cannot assign missions to the air units if they are in the reserves, and the "move to front line" button for the air units was grayed out, so I couldn't use them at all. I think the fix could be not allowing air units in the reserves, or coming up with a way to assign air units in reserve to a specific mission.
Otherwise the Caporetto scenario ran fine with 105a.
