So I have the regular Wishblossom Ranch DLC but I recently learned that the Sven Mount is actually only in the deluxe edition. My question is, do I have to re-buy the deluxe edition of the dlc at full price to get the Sven Mount? I tried googling it but for some reason was having a hard time finding an answer so I came here to ask instead
