- Added four new fields to DS config file:
<MaxHP>
<MinHP>
<MaxRecharge>
<MinRecharge>
- These allow you to set a flat maximum and/or minimum for shield HP and recharge rate.
- MaxHP specifies a maximum value for any shield at full charge, even if the grid would ordinarily have a stronger shield.
- MinHP specifies a minimum value for any shield at full charge, even if the grid would ordinarily have a weaker shield.
- LargeShip, SmallShip, and Station ratios are applied after this cap; i.e. with <StationRatio>200</StationRatio> station shields could have double the cap.
