I set 'disableInventoryCrafting' to false but it still works, not sure if its me or not. Any idea of why? (to not upload file elsewhere I changed extension to log from cfg)

primitivecrafting.log

I have this same problem. It doesn't work when by itself either

I can't really recreate this... could you show me a screen of your inventory?

Sorry for the late reply (kinda forgot about this)

(top right is the game, left is my config file, line 13 is disableInventoryCrafting while the bottom is the mods folder for my instance)

Do you have any other mods that alter the inventory in any way?

I have reproduced. Additional mods that might conflict include FastWorkbench and Patchouli. Here's a Debug Crash report so you can see the list of mods for yourself: https://pastebin.com/FXhbED5T

sorry about long delay in my reponse. But I was only using your mod when I posted said report back then.
