Three of the same mistake. A torso-mounted cockpit counts its centre torso's plate a second time and has to count the plate still there - a stripped Enforcer III was paid twice for armour it had lost. An armoured system slot stays worth something when the slot is shot out, and modular armour the same: MegaMek pays for the plating whether or not what it protected still works. And a Banshee writes `Hip (ARMORED)`, which the leg-damage rule missed for want of stripping the marker - it walked as though its hip were whole.
