Gnomishness

I left the Dungeon to observe one of the "fearsome red" creatures. After that, when capturing the last Dwarven city, the script prevented it from entering the Dungeon. I reloaded the save and observed all three. Now they are just running around in the snowy field... And yes, the red army didn't increase in size either. But I was using cheats, so maybe that's why the bug occurred.
