So I managed to complete the campaign tonight, miraculously due to no saves, and I think I've noticed a few issues between skirmishes, and simply on the map, when playing too long and looking at cards.
First of all, I'd like to mention the cards, I don't remember when it was but suddenly the cards stopped drawing some of the artwork. You could see the cards outline, and information on the card, but the image has disappeared.

I've noticed later that the issue only grew worse after that turn, none of the cards from that UI would show the artwork, or in the card shops. The card collection UI and the screen to select your cards in battle, they show properly.
The second issue, being in the skirmish map I think was a subtle bug, I may be wrong in this assumption but I'm pretty sure it was a minor bug.
After having bought a few skills from the map for the Dragon, I'd be re-arranging skills for him just before launching the skirmish. At one point I had the blood leach aura on about hotkey 7 or so, later I simply dragged a different aura skill ontop of it, to dimish their hp, pretty sure it was hp, however later in battle even though the graphical effect above the units still showed, it wasn't really any easier for anyone to kill the enemy units.
Active skills when changed in the same manor seem to be ok, because I changed a few around with, or replacing with, active skills which seemed to work completely fine. Later however I replaced the passive skill that I've been noticing with another passive skill, I don't remember which one, but I simply no longer was using the blood dragon aura thing, I was out in the field, I know I had taken some shots from some grenadiers, but every fireball that would hit, seemed to increase my health by 20 point, I was able to see clearly and calmly later when they weren't shooting at me, I was low on health, and I was burning down a transport, that was preoccupied. :P
