Everything works fine.

I would like to chim in stating that I can reproduce the issues as stated here and it comes down to NanoLiveConfig check for FabricLoader just checking if the base event module for FAPI is present which seems to have changed within later versions but not within the latest version of radium for 1.20.1 gotten from curseforge

Everything worked in older versions of accessories, I thought it was a skills issue.

Hey @fg1989 and anyone who stumbles with this problem.

I faced the same problem, but oddly enough, I fixed it by adding connector and forgified-fabric-api to my modpack.

Apparently, given some unknown condition, some mod tries to access Fabric API classes in a NeoForge enviroment resulting in a ClassNotFoundException

@diefesson Its an issues specific to mods using the version of CaffinieConfig(NanoLiveConfig) that has an improper way of checking for Fabric Loader that needs to be pulled and an update made for such that has yet tot occur. However the above method dose fix the issue temporarily for 1.20.1.

I want to point out that other mods are also checking for FAPI in a similar way and many people facing the problem will also end up here. So it's still a valuable knowledge for those.

Working on it!!!
