with your mod installed NEI lags and the console spits:

Looks like this is actually a bug on TiC's side that would actually cause a crash if you ate the food causing the error (bacon gotten from pig iron tools). I will make sure to stop the console from getting spammed, though.

Also note that the 1.7.2 version of Tinkers Construct is officially unsupported and downloads of it have been pulled by the TiC devs, so any bugs in the 1.7.2 version of Tinkers Construct will not be fixed.

Which version of TiC?

no, that doesnt work on 1.7.2

Sorry, my brain doesn't work. Meant to ask which version of TiC you're using.
