Us is no longer able to carry items and use consumables.
Looks like Lae'zel and Shadowheart lost this ability as well when the party is on the Nautiloid. At least I can no longer use them to carry all that explosives to the helm - their inventories are inaccessible, and they can't pick up items lying on the ground. Happens regardless of having Us in the party.
You can still give them items by dragging an item onto their portraits.
