mc 1.20.1
Forge 47.1.3
mod: smartbrainlib-forge-1.20.1-1.12.jar

not sure what happened? either you purposely uploaded the wrong mod file or were unaware that anything above forge 47.1.3 was currently broken beyond repair. but the latest update is calling for forge 47.1.4x instead of 47.1.3. just giving you a heads up. I had to downgrade to get it working again.

I've added this comment to the file, and renamed it to Broken Forge to help clarify

This is a bit of a complex situation because of forge breaking stuff

I might add some more information to the file on curseforge or something, but I'm always going to be between a rock and a hard place

SBL-Forge-1.20.1-1.12 is specifically for the newer forge versions (47.1.28 and above), with the changes necessary to make it work with Forge's changes
You should be using SBL-(Neo)Forge for anything underneath that

Reason I mentioned it because the forge devs themselves recommended everyone to stay on 47.1.3 until neo forge was available everywhere. And currently cant use neoforge on curse yet (where my modpack is currently)

Yep

Like I said, it's a bit of a tricky situation
This file isn't for you, if you're staying on 47.1.3 or below, or on NeoForge

I've also removed it from the forge/1.20.1/1.20.2 markers so that it doesn't auto-promote itself

Alrighty then thanks for that
