Minecraft keeps crashing.

Unity · July 10, 2019

I am getting a crash on launch saying:

"ava.lang.ClassNotFoundException: net.minecraft.item.BlockItem"

I have quite a few mods. How do I fix this?

What mods do you have? Are you on 1.14?

Sorry for the late reply the day after I wrote the post I went driving to Nebraska from Colorado. Visiting family.

Just got time to get set up again.

And I am aware some of the mods are not for the correct version. but I don't care too much tbh.

You should care, because of API changes in newer versions of Minecraft!

You can't use 1.14 mods with 1.12 because of the massive API changes! I bet bookshelf 1.14 is the problem.
