I am trying to make a modpack but i cannot start it with Tsteelworks enabled. i am not sure but it seems that Iguana tweaks "stack size changes" are causing Tsteelworks to crash on start...
here is the crashlog http://pastebin.com/qjpTp0Q9
awesome mod btw I used it in my 1.6.4 pack (was a very unbalanced and just throw as many mod together as possible pack with no changes) ...but i am planing on making it the main way to get steel in next pack.

Edit managed to get past this

Same as #18, I don't have a clean way of solving this right now. Don't close the issue I'll close it once it's fixed

I upgraded to IguanaTweaks-1.7.10-Beta-19 now i don't crash
checked the change log here looks like the bug was not in your mod https://docs.google.com/document/d/1PO0dO5VKVWrg5sxTrDieAICLY5Ap9J7rzgpIncoJn1k/edit

Oh, weird because that looked like I tried to add something that did not exist to the oredict. Did iguanatweaks remove something ? That would explain why boni asked for a nullcheck
