Skyblock Rank Problem

Hey Guys. Do you know exactly when skyblock's rank will fix? Thanks for your attention.

 

Which command did you try to use that brought up that error?

 

The /is rank command does not work, nor will it ever work. That command has never been used in the past.
The command itself would normally show the person with the highest calc (can find your calc by doing /is calc)

But nonetheless, there isn't a fix on it.. or that us normal players know of. Either way, kind of a useless command.
