Game Crash when looking at an anvil with a pre-mod used hammer

[Hershbja]

I am playing singleplayer that is not open to LAN or internet. The mod was installed after the world has started and with a used hammer.

My game instantly crashes when i look at an iron anvil with a meteoric iron hammer with the current tool mode being in split mode
(After more crash testing. it doesn't matter what mode the tool is in or what material the hammer or anvil is made of).

I have disabled all code based mods (minus the game itself) and it proceeds to crash every time i look at the anvil with the hammer in my hand.

I would check to see if GetChannel(ChannelName) actually returns anything. It might be returning NULL.
