just kidding, its still broken
The issue has been solved, delete the config and start again, the server will set itself back up!
For whatever reason I can't load into my forge server, it was working before but now none of my previous versions are working!

I did try to install TConstruct-1.12.2-184.108.40.206 and conarm-1.12.2-1.0.2 but it didn't work. so I went back to the old version of tinkers. Could it be that I have to different versions of tinkers construct hidden somewhere?
