Had an interesting experience in the game I played last night. I was in a fight with one of the big boss monsters, just a bunch of archers and mages against the big rock monster elemental thing. He was in the process of killing my archers one by one, when suddenly he stopped moving. For as many turns as it took for my archers and last mage to kill him, he just stood there. Which is a bug, of course, but not the one I am reporting. What was really annoying was that it listed his loot on a popup window, and because I had no hero in the battle, it just disappeared. This has happened to me before, and in fact happened a little later in another battle (Just a wolf skin that time.)
If there is no hero in the battle, the loot should either not be reported (not the best fix), go to your sovereign, or something. In AOW, they had a little bag icon that appeared on the map.
