Crash when smelting Iron ore berry in Smeltery

[f03n1x]

As title says iron oreberry seems to crash when put in the smeltery,

Here's a pastebin, but it's an array out of bounds exception: https://pastebin.com/g1c4D76G (I'll post the first less detailed stack trace)

The bug is fully reproducible, so far I've only tried twice (first time being without knowledge) I can provide my save if need be.

Steps to reproduce bug:

• Get iron oreberry and place in smeltery
• Wait about 1-2 seconds for smelting to begin
• Client crash

The current version of the blightfall modpack for me is 2.1.5 (latest)

The only difference from the standard modpack is that I added in Optifine (OptiFine_1.7.10_HD_U_D8)
