@PCDragon3979 I noticed a limitation on the unique units that the player can create with different civilizations (e.g. Franks creating the Leitis, Turks creating Qizilbash Warriors) in several campaigns of yours. None of them can be upgraded to their elite versions, even if the player starts in the Imperial Age or can advance to it. This greatly limits the use of these units in the campaigns.
Another bug I found specifically in the Louis XII campaign is the presence of the Bearded Axes tech even though the French in the campaign cannot train Throwing Axemen.
