So I played 1.0 and joined Twin Adder and got the GC Choco from it. Now that I'm playing 2.0 and re-rolled to Maelstrom I was able to keep the Adder GC Choco, but tried to get a Maelstrom one but I can't get a Maelstrom Barding on it. The item doesn't even show up to be purchased with seals.

Does anyone know how to fix this problem?
