I have Medieval Madness (Remake - LE) and everything SEEMS to progress normally until the drawbridge lowers. No matter how many times I hit the gate, it doesn't seem to register a hit or open. If I have all 3 balls locked, the ball either just drops into the moat (when shooting the side) or bounces off the gate. Is there a switch that needs to be fixed, moved, replaced or something else to trigger the gate to open? Thanks!
