Have had trouble with a couple of bugs. I'll attack adventurer groups, it'll tell me they're no more, but they'll continue to exist anyway. I've also had the game freeze when searching for new lands to conquer, this being the second time in my current playthrough that I've done this.
I'm playing on a debug difficulty (69) and have used 777 multiple times, so I'm not sure if that would have anything to do with it.
