Whenever I try and run this mod in Minecraft, the game gives a NoClassDefFound error. Does anybody know how to fix this? Here is the crash log:

FML: 39.0
Forge: net.minecraftforge:39.0.9`

Starting with version 0.1.4, the mod doesn't ship TKLib anymore due to some issues in Forge's mod loader.
You can get it here: https://mc-mods.cf/technicalities-lib

I forgot to mark it as having a dependency on the lib, so you don't get the nice error screen and it just crashes instead.
I'll have a patch for that and a couple other things out very soon.

Thanks for reporting it!
