Do you love using Self Switches as Page Conditions?
Are you worried about mobsters leaving worthless treasures that the player will never ever pick up and pack them?
You don't want the player to see those useless spoils are still lying on the floor when the party returns to that map?
Then I have got a solution tailored especially for your gaming needs!
With just a script call placed right after the player has defeated the enemy troops, you can tell the map to take care of just those events that would look totally out of place once the player returns to that map.
