I was just playing and notice that when I went to a town to create a forward observer (2 units same name but one with daggers and the other with an oak spear). When I click train unit the first FO picture is him holding the spear however the popup card shows a dagger. The 2nd FO shows the correct weapon on both picture and card.Another time it was reverse with both units holding an oak spear.

When I go into the roster the units are properly displayed.

I attempted to record however I am on the rear end of the internet and upload would take too long. I will try to upload my save file if needed.
