Server / client crashing in relation to lava buckets and invisible items.

Crash Report

What happened wrong?

I was originally having a problem when i placed a lava bucket in the furnace it would crash my game, Later I also noticed that several of the items and upgrades were not visible when held in my hand. Lastly, i added the factory upgrade to my furnace and it crashes my client and server as soon as I enter. I'm guessing this is some compatibility issue but i have so many mods it would be extremely time consuming to attempt to enable and disable mods to narrow it down. I was hoping my servers crash report might shed some light.

The crash with the lava buckets also happens on a new world with only better forge and factory api installed.

Fixed in 1.1.2518.1, thanks for reporting.
About the invisible items, I don't think this is related to BFR, as it uses vanilla item models, certainly it's other mod causing this.
