Edit: This bug has been fixed for me and is no longer an issue. Now that the buyback cost has been fixed (thanks again), it's creating a problem with a shop's ability to "sort by cost" correctly. From what I can tell, sold items are being sorted according to what they'd cost were they sold normally, and not an item being sold at it's reduced buyback cost. This is causing the store's inventory to become a frustrating jumble of new and sold items, especially Randimar's because of it's low refresh rate. Here is what a couple pages of my Randimar's window looks like right now if I'm trying to sort by cost: Basically this is just sorting by quality right now.
