If you are missing your rank on any servers, go to this link - https://store.manacube.com/category/1059611 and reclaim it. Make sure you are online on parkour or the server you are claiming it for at the time, and you should get your rank within 1-30 minutes. If you are still having issues after this, open a ticket here - https://manacube.com/support/
I will be moving this thread to the main parkour forum as this is not a locked rank appeal.
