Getting this on startup:
[21:59:47] [Server thread/WARN]: [mcMMO] Loaded class net.kyori.examination.Examinable from spark v1.4.3 which is not a depend, softdepend or loadbefore of this plugin.

mcMMO developer stating it's an issue on spark's side (@nossr50)

Fixed via: mcMMO-Dev/mcMMO@a39c742

My bad, I wasn't properly relocating that library.

Ah, seems like I'm not relocating it either, will fix, thanks!
