Witchery tem alguma recipe quebrada

[Eufranio]

Quando um crafter do AE2 tenta criar um Fire Protection Poppet (aparentemente), ele crasha com isso:

java.lang.NullPointerException: Ticking GridNode

por que a saída da recipe é null (aqui: CraftingTreeProcess.<init>(CraftingTreeProcess.java:80)), e passa essa saída para o ItemCraftedEvent, que passa para os outros mods que não esperavam um item nulo e etc...
