ok, interesting... that shouldn't happen at all. There is one crafting recipe that has an empty result. Do you have any other plugin that registers recipes?

Yes I am using itemsadder. Also it was a fresh install from custom crafting. I have no registered recipe yet. I have some furnace recipe with itemsadder
