So i watched a video on how to configure Spartan Weaponry with Epic Fight, but it's just straight up not working. whenever i put in what i typed into the config, this is the error i get. any solutions?

If you are playing on 1.16.5, try this config.

Do you have a crash repo?

No not anymore, I managed to fix it with the config that the other user sent me. Though, I still do have a problem where if I create my own my config then it says "epic fight has failed to load correctly" or something like that.

It would leave a message in a log file if Minecraft failed to load.

I've gotten this error in the past when I had a double entry, could be the cause.
