Gemstore through the app appears to that the Unbound Magic Gathering Tools are available while in fact arent , just pointing it out...guess those gemstore items are not subtracted by the API but made manually?
or is it just me ?
The way I update the master list is by using the in-game "Promotions" tab, which ArenaNet posts items that was recently added or will be removed.
I probably forgot to remove those items when they appeared on the Promotions tab. Or if ArenaNet decides to remove them without warning, I would totally miss it, because I don't do a complete check of the in-game Gem Store.
I've removed them from the wishlist so you can now subscribe for availability instead of discount.
Thanks for reporting.
