so for clarity, there are two bundles that contain The Surgeon sniper rifle model. while it's being offered in two bundles, as soon as you purchase one of the two offers, you should then be offered the "fallback" offer that is the rest of the contents minus the weapon model at an adjusted price.
what is happening now is everyone is seeing the default Hivebreaker Bunyip bundle, regardless of whether you possess the sniper or not.
they have already found and updated the issue in the test builds to make sure that those who own The Surgeon see the backup Hivebreaker Bunyip model.
that update should hit the retail game soon. :)
