CRAFTBOOK-2994 - Reported by Kainzo

So, before (months ago) using custom items to craft other custom items didnt work.

Now you can use custom items (and only custom items before any item of the same data value would work)... however.. you cant use multiple different custom items to create a new item.

here's an example.

With using basic craftbook, I was able to do this.

STONE-A + STONE-A = STONE-C
However, I was not able to do this...
STONE-A + SAND-B = SANDSTONE-C

here's my recipe im trying - http://pastie.org/private/lyh7nzqa2exjqesxgfizyq
Thanks!

This is most likely due to Spigot's bugs with post-flattening items
