Sometimes (MOST of the time), when doing the spy node for kuva fortress, the hidden panels that you can destroy to complete one of the spy vaults seem to be indestructible . Weapons/melee doesn't work. Neither does operator. Using warframe abilities seem to work tho (used seeking shuriken so far).
I looked into it and seems this bug has been here for YEARS already!?
