If your logs are spammed with Unable to grab ViaVersion client version for player!, that's because the library "packetevents" in one of your plugins is doing something dumb and not ViaVersions fault!
Download findpacketevents.sh and run it (via the terminal/ssh) in your plugins directory
Download find-packetevents.ps1 and run it (rightclick → execute with powershell) in your plugin directory
