I am making a survival server, and there are some features on 1.16 i dont want to be on my server, so I downloaded protocollib and theres no config, I need my server to be on version 1.12 not 1.16 and also block 1.13, 1.14, 1.15, 1.11, 1.10, 1.9, 1.8 to be able to join, is there a plugin / skript to detect this and kick the players that arent on 1.12.2?
