Trying to load a fabric modpack and it wont let me due to something related to the collective mod!

Uncaught exception in thread "main"
java.lang.RuntimeException: Non-unique Mixin config name collective_fabric.mixins.json used by the mods collective and collective-fabric

Make sure to use the [Fabric & Forge] version files for all mods. And remove collective_fabric, since it's been deprecated. Thanks for the interest!
