i am using this plugin on my modded server and I wanted to have a quest to craft certain item. So i used command /q obj add craft 21271:1 1

But when I craft this item on crafting bench it doesnt count towards the quest. I also tried just putting 21271 without any meta-data, but still nothing :(

Modded servers are not officially supported. Quester relies on Bukkit API, and custom items aren't part of it. It should work in most cases, but it's not guaranteed.
