Interact wit rubble??

So I am playing Mission VI (Vet, XBOX) and my Sergeant stands with his back against rubble ... and I can Interact with the rubble (0 cost and nothing happens)? Another bug?

Rubble is something you can destroy.

You therefore need to shoot at it or use a melee attack.

Interacting with a console can open doors and program turrets.

Interacting with rubble with just give you dirty armour.

Shoot or smash.
