The Noteblock recipe for example, in the assembling machine it normally requires 8 planks and one redstone, though wood from Forestry, which is ore dict correctly, only requires 1, despite the fact that its still 4 planks from a log like any other wood.

First pic shows Extra Trees wood, it asks for 8, same for Vanilla wood

Second shows Forestry wood., it only asks for 1

Lastly, this shows both wood types are ore dictionary correctly.

Are you saying it works fine with forestry but not extra trees?

Wasn't sure at first, but its Forestry wood that is working incorrectly.

ok thanks

hmm It it uses the ore dict so im not sure whats wrong

It should work fine, RecipeHandler.addRecipe(new AssemblingMachineRecipe(new ItemStack(Blocks.planks, 8), new ItemStack(Items.redstone, 1), new ItemStack(Blocks.noteblock), 120, 5));

This appears to only be an issue with the nei handler

I found this and this is bad:

You override the oredictionary. Please copy the itemstack instead of changing the name of the orereference! This could be also your bug...

Oh, :) that looks like it! Let me test
