The "Merchant & Mender" NPC at Central Shroud (X:23.1 Y:19.4) sells weapons.
In the weapon list, the order goes from lower level to higher (and price), except for:
Maple Wand
Whispering Maple Wand
These are reversed w/whispering on top. May or may not be considered a bug. Have seen this elsewhere (i.e. weathered items always appear as the last of their group, though that seems consistent so is likely intentional).
