Game 33749 - Darklords 53 just in case you can check game logs.
I placed my Barb + 3 other units on a dock to end my turn (turn 8). I upgraded JUST my Barb to the best boat since he was the lead unit in my fight order and could easily defend the other units. Next turn I click to move to attack an enemy AI stack of 4 barges. To my horror my Barb is fighting in his own barge instead of a Galleon and I am slaughtered.
Not sure if this bug is because I only upgraded 1 unit or because my stack stayed on a dock so the upgrade didn't take properly. Either way something went gamebreakingly wrong here.
