I've encountered the following problem and thought it would be worth a share: The Item Synthesis Plugin works fine, but in the synthesis ingredient notetag, only items are registered. any armor and weapon ingredient is completely ignored. it also doesn't matter, whether you get them via name or ID. Notetag for an Armor: <Synthesis Ingredients> armor 3 --not registered item 32: 3 -- registered item 47 -- registered Brestplate: 1 -- not registered (via name) Potion: 1 -- registered </Synthesis Ingredients> Did anyone encounter the same problem? If not, am I missing something? I appreciate every help.
