Hi! I recently deleted Autorank for a few days and when I put it back up, some player that has had their rank changed, can't check their stats with /ar check. I didn't use mySQL database and I had already deleted the whole AutoRank folder and start from scratch. Everytime they /ar check, it says
An internal error occurred while attempting to perform this command

In the logs, here is what I see:

Please help!

EDIT: after a few hours, some new completely new players did /ar check and their rank didn't change and their playtime is 0 minutes
