Missing wood Floors

seem to be a weird bug or glitch with some wood floors, in the mission Recover from Airship on port Nazaru the floor of the wrecked ship is missing, so the chests are floating in mid air, making really hard to be recovered and complete the mission, also the woden floor on blackdager wher the gnoll harper spy is, has dissapeared, only the base wood is there, making difficult to walk towards him, it's not really a problem, but it's very weird.
