Finally fixed a MASSIVE update error. (For now, I'm keeping the version as v4.5.3 on Spigot, to allow server owners to update and fix this issue before this error is thrown again) (Bumped on 11/17/19 to v4.5.5)
Removed /spook for it is no longer the season of spooks. (Look forward to some festive feelings!)
Cleaned up the house and squished a bug or two!
It is highly recommended to update to this version or newer immediately if you're running v4.4.X or v4.5.X series, as this update fixes a big error that can be thrown when a new update is detected.
