[Leon.8371]

Hi, so I was trying to get my hands on some gold and I have come upone the following recipe : https://gw2.fandom.com/ja/wiki/Cured_Hardened_Leather_Square,which can be found on the wiki too : https://wiki.guildwars2.com/wiki/Cured_Hardened_Leather_SquareProblem is that after I have tried to follow the recipe ,whenever I add the "Cured Thick Leather Squares" I am unable after to add "Hardened Leather Section" and vice versaI have tried asking around and didn't get any response,can someone offer me some help regarding this problem ?(I have stacked myself with lots of cured thick leather squares and can't do nothing with them rn )

Have you tried adding them in a different order? Sometimes it bugs.

[Khisanth.2948]

That is a pretty common issue. Usually you just have to reopen the forge window or change the order you put the things in. Occasionally you need to restart the client.

I'm pretty sure it should both be either the raw or the refined versions, so if you are going for the squares you should throw in '250 Cured Thick Leather Squares' and '1 Cured Hardened Leather Square'. The wiki has it wrong.
