Additional context

you MIGHT be able to make those mods not require it just by jar editing, which should be simple for connector to do (since it literally modifies fabric mods)

well i dont have kotlin for forge installed, and i saw in the logs connector talking about kotlin, and i remove connectorextras to make sure it wasnt that.

[awesomebossdj7]

also what i meant by jar editing is turning file into zip and removing kotlin dependecy, which did not work, for industrial revolution

connector has kotlin for forge built in

Pretty sure it doesn't? Fabric Language Kotlin works perfectly fine on forge. Please list what mods you're using as given in the issue template.

ah, it was essential mod, should i make a new issue?

[awesomebossdj7]

its compatible with connector (if u download forge) but if you try to use it with a fabric language kotlin, it doesnt like it

essential does have fabric version however

[Su5eD]

After looking at the layout of essential's jar file, it appears that they're using a custom mechanism to load KFF at runtime, since bundling KFF as a regular jar would result in a crash as described in MinecraftForge/MinecraftForge#8878.

Unfortunately, due to Essential's closed source nature, I'm not able to further determine the exact cause of the issue. However, it is apparent that this is a result of the custom KFF loader, as KFF itself works normally alongside Fabric Language Kotlin when loaded from the top level (mod folder file).
