I have this mod installed on a quilt client (via setting up a new mod profile on curseforge with quilt selected) and mischief keeps saying I don't have geckolib installed, although I do, and I can't open the game. I'm assuming this is an issue with using curseforge, but I'm not very good at troubleshooting so I figured I'd just ask here

also, I may be stupid so consider that too

You have geckolib 4, not 3.

Also RAT's Mischief is only updated to MC1.19.2 and will not work with newer versions of Minecraft.

heck

Make sure you are using the correct geckolib version

I am

Can you post the exact error message, along with a screenshot of your mods folder?
