For whatever reason, KMS created a new NPC for the updated coin shop (named Squire Pancho Sanza), whereas the old NPC is just named Pancho Sanza. They replaced all the Pancho Sanza NPCs with Squires, but since Momijigaoka is non-KMS, it seems that GMS missed the memo on that one. Why KMS couldn't just reuse the existing NPC ID instead, I don't know, but they love to bloat the game.
So it seems Nexon made Oranges unable to be sold to NPCs, meaning that they don't show up when trying to sell items. Unfortunately, that means that you also can't recharge them. An interesting bug if I say so myself
We won't be getting it unfortunately. We used to have the JMS version, but they removed it in favor of the KMS version. JMS did a lot more with theirs, such as replacing Azwan with Tower of Trials and creating a blockbuster for it with a new final boss, but that's only in JMS and TMS now.
