Apologies for the short notice, I'm going to be updating the hub tomorrow at 2PM to update the hub with the work the MB Team have completed, and as part of that the server and it's plugins will be updated to Minecraft 1.17. There's quite a bit of work to do as part of this update, so we're expecting it might well take a couple of hours. As we don't have a dev server for the hub server it might also be a bit of trial and error.
Updates will be posted here: https://status.atlas-media.co.uk/issues/2021-12-05-tf-hub-updates/
