Hello
@purable!
What version do you typically play KitPvP on? I believe the recommended version is
1.8.9, so you should try that out if you don’t already. I’d also recommend trying out OptiFine and/or the ‘Badlion’ client if you’re on a windows PC. If the issue still persists, it could be a server-side issue, in which case you’d just speak to a member of staff and they would ask for a reboot if the server badly needed one.
