First some background, we use Floating Crit rule.
So my side has a mech which took a floating crit to the leg causing a foot actuator hit. However the armor was not breached, and there was no damage to the internal structure.
So do I need to pay for internal structure repair cost to fix the foot?
My take is l would, but I have the option to just repair the armor and leave it limping until there is IS damge to repair.
