Use mods items with catserver

Created by: SparkGNRK

I use catserver to support forge mods with spigot plugin (catserver is a fork of spigot like cauldron but very stable), when i want to use an item of a mod (like custom npc or variedcommodities) MMOItems say that this is not a valid material ID (i've tried an old id like '179', variedcommodities:diamond_greataxe and DIAMOND_GREATAXE). The plugin work very good and not make error at all in catserver.

Describe the solution you'd like Can be able to use external material id. (all other plugin i have work good with mods item like chestcommands)
