Whenever i try to replace parts on my tools the game crashes. I'm running the latest version of both ITT and TiCo.

Forge Version: 10.13.4.1492
ITT : 2.1.5
TiCo: 1.8.8

i do not see any thing that says iguana tweaks was loaded in you crash log

Nor TConstruct, for that matter.

That's weird because i'm know i'm using both because i have all the crafting items and the tools and i know i have Iguana Tweaks because i was in the config file uping the max level of tools.
