1.12 - Mod crashes without Tinkers Construct installed

[MattJohns]

Testing without Tinkers Construct, just the mod (and the associated library). Set stone to harvest level 3. As soon as you swing at stone it crashes with:

Oh my, looks like something loads that shouldn't load. I don't know when I'll have time to take a look.

Having the same issue here, would be great if a fix gets put out soon, till then I have to remove this from my server. :(

[The-Arcanian]

I am getting it when hitting stone with a stone axe, but not a stone pickaxe. Also going to have to remove this until it is fixed.

[pixzi]

i got the same issue, just by punching with my hand. Strange as the only thing i changed was the ability to not much wood.

Hey!

Two years later, no fix for this problem... =/

[bonii-xx]

Oh, yeah. I forgot about this. I don't really have the time to keep this updated, sorry.
