This is mainly for new players, but also for players who might need this information. First of all, I strongly agree that not the majority visits the Forums daily or even at all, however for the minority who does, thanks There were quite a number of new players or even some players who've taken a break and returned a while ago who were constantly kicked for unknown reasons and they were clueless about it. Our current Anti-Cheat system reacts extra-hyperactive when a player walks on snow or slabs or swims on water, especially when the utilized minecraft version is 1.13+. Therefore, for best resolution, use 1.11.2 or 1.12.2. It creates least errors possible and improves your gameplay overall. If it lags in the game severely, I also recommend you to install Optifine client. It is a client that is meant to improve your FPS quite effectively. Thanks
