Hi,I've seen the same issue like with https://api.guildwars2.com/v2/guild/upgrades/840Sometimes we can have :"prerequisites": [] Instead of : "prerequisites": [ 253, 424 ],With Postman it's almost 100%... { "id": 840, "name": "Guild Hall Music: Super Adventure Box", "description": "Visit the minstrel at the tavern to change the background music of your guild hall to a selection of themes based on Moto's Super Adventure Box.", "build_time": 0, "icon": "https://render.guildwars2.com/file/96E17707772DCB56487E9EE5D84C1C3E034D7A6B/1202618.png", "type": "Unlock", "required_level": 8, "experience": 35, "prerequisites": [], "costs": [ { "type": "Collectible", "count": 128, "name": "Guild Favor", "item_id": 70701 }, { "type": "Item", "count": 1, "name": "World 1 Super Boom Box", "item_id": 46500 }, { "type": "Item", "count": 1, "name": "World 2 Super Boom Box", "item_id": 46504 }, { "type": "Item", "count": 500, "name": "Continue Coin", "item_id": 41824 }, { "type": "Currency", "count": 256, "name": "Aetherium" } ]}Any way to get it fixed?
