I’ve been getting this bug by:
Starting a new game on Deadly. As soon as the game loads click on the nearest village and start moving toward the village. When I get to the village the introduction battle loads instead of the village. After the battle there is a short buzzing sound. Then the village loads and I agree to to after the Weasel or not. Either way I get 40,000 to 60,000 gold.
I have tried to duplicate the bug several times and the key seems to be to get the party moving before the introduction battle starts. If I wait for a second before moving when a new game starts the intro battle loads and the payout at the village is normal.
