Upon joining the server at one particular point, luckperms gave this warning, and subsequently I was unable to type any commands presumably due to a lack of permissions. Relogging fixed this.

What LuckPerms version and Spigot version are you using?

Update: https://luckperms.net/

My bad, here's a timings report that shows all that:

Thanks for reporting, should be fixed in the latest version.
