CB Paid Subscriptions

User A shares Plan X with User B and User B upgrades to Plan Y causes Plan X to be replaced on User A. This should not be possible. Either the upgrade should be blocked and the user told to cancel or it should automatically cancel during the upgrade. User A should never be impacted in any way and the dummy objects should be preventing that. This suggests there's a storage process somewhere that isn't using the objects and is just directly doing database stores based off object id. Maybe clear the id as well to prevent this.
