Hi everyone. My first post and its a panicky one. Love this game a lot, exactly the type of game I've been looking for. I'm messing around in the Scenario and I've gotten to the quest "Gates of Redstone". It tells me that Warlord Verga's army has occupied  three of Redstones nearby granaries and that I need to go kill em all. I did so (and thouroughly enjoyed it fyi) but when I go back to complete it I get "You have not yet defeated all of Verga's soldiers". I've been scouring the entire landscape everywhere and there is in fact nothing else for me to kill. I've got four armies looking and i've been moving them around for more than 100 seasons now looking. Naturally spending this much time looking about has pretty much saved over all of my autosaves so I can't load back to before I killed the troops.

As far as killing the troops, this went quite smoothly. I killed all of them with my heroes and I've turned off auto end turn so I don't know what can have gone wrong. Any help would be appreciated. Thank you.

Edit: Oh, I should also add that the keep is burning so it's seems to have trigger, but looks to have bugged somewhere along the way.
