Subtle nuance: Perhaps the point of the R5 Astromech is for *EXTRA* supplies? Nowhere does it say the R5 is interacting with the crate to claim it, just that they get to draw a supply card with a limit of once per crate. The crate would still be in play for a hero to interact with it, claim it for another supply card, and then score the credits at the end of the mission.
