You're right that this bundle was not properly granting the Free States Vending Machine Skin to players who unlocked it in the Atomic Shop. We've fixed this issue now, so all future players who pick up this bundle will receive the Vending Machine Skin correctly.
We're also going to grant the Skin to you and any other players who should have received it within the next couple of days. Thank you and we apologize for any inconvenience in the meantime!
