Weapon DamagedPlace 1 of the Hardpoint Upgrade cards equipped to this section under this card. You cannot use that Upgrade card while this card is faceup.Energy: Spend 3 energy to flip this card facedown.

So yesterday I played an Epic game and this case of figure happened.
My Raider has Ordnance Tubes equiped with Cluster Missiles and it receive a critical hit dealing the Weapon Damaged card. What happens?
Because it says to put an Hardpoint Upgrade card under the card, but it doesn't have any Hardpoint Upgrade cards equiped, only Missiles Upgrade cards.
We rolled the decision and I kept my missile, but it would be nice to have a sure answer to it.
