Posted July 5, 20178 yr Hi, sorry if the title is not very descriptive. I don't know how to describe what's happening to me. Today I wanted to continue with my very basic mod, the Pen Pineapple Apple Pen mod. This is just a project to learn how to make better mods actually. The thing is, it has an incompatibility problem with Extra Utilities 2. So I wanted to fix that and in order to replicate the issue, I dropped the Extrautils jar inside the mods folder of my workspace, but it crashes with the following error: Spoiler ---- Minecraft Crash Report ---- // Would you like a cupcake? Time: 05/07/17 00:06 Description: There was a severe problem during mod loading that has caused the game to fail net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from Extra

Project is running Java 8 (update 72 if that's a problem). I could update it if needed. Thanks.
