The LagGogglesCommand class references the class cf.terminator.laggoggles.util.ClickableLink - however, ClickableLink is not in the repository. I suspect that you have this file locally, but forgot to commit it.

Well snap! I think I may have to decompile my own mod to get that class back. I have no backups. Good find!

I intend to re-make all of LagGoggles anyways for performance enhancement

Welp! Thanks to the locate command I used on a backup of my old OS I found the file. It's a tiny file, in fact.
