That did the trick, thank you very much!

Ahhh I think I must've used one of the mask parts, maybe? There might be parts from the DLC you haven't unlocked, I think you can unlock all the parts fairly easily though if you don't want to play through it:

Unlock Champion Road Beyond: Highlight the Champion Road -> Champion Road Beyond button, press and hold W+D then hit enter. (got this from Carlzilla on the Modpack server, haven't tried it but it should work, lemme know if it doesn't just in case it's a problem with a part I've used or something)

I'm having an issue with this, I can seem to use it. It says I need the Champion Road Beyond DLC when I have it installed. Any suggestions?

Awesome, thx
