Hello Bdew!, I got this crashlog after i removed some of the hammer recipes i didnt feel were appropriate to the HQM-based Map i'm making ^^'.

Crashlog:

Script:

I can't reproduce this, tho i didn't try with all the mods mentioned in your file.

From the look of your log you end up with null entries in the hammer recipe list, i'll try adding a workaround.

Well onto the next mod dev, 1.) NEI dont registers the Modtweaker change properly but it doesnt crash. 2.) this happens when you try breaking a block: http://pastebin.com/6aPYcxvc

Well whatever put those nulls in there (i'm not entirely sure it's modtweaker fault) is messing up Ex Nihilo in the same way it was messing my mod :P

I'm going to close this as it's supposedly fixed. If you manage to get the changes to work with EN properly and they still don't show up in NEI - comment here or open a new bug report.

Will do, Idk why it would do this either. The Sieve removal recipes works perfectly however Hammer Recipes is the thing causing issues >.>
