I have just been whitelisted and can get in the lobby and in creative, easy and skywars, but when I try to get on pvp it says I am kicked out because I am sending too many packets. What does this mean? I only joined because I'm desperate to practise pvp! Thanks!
Being kicked for sending "too many packets" usually occurs if someone is executing too many inputs in one of our worlds. For example, if someone sends too many commands in a short period of time, it may kick you for this reason. In trying to go to Arenas myself just now, I experienced the same issue, so I will make a bug report about it. It may also be worth checking which version each world is in. Arenas is in an older version than the rest due to some of its plugins that it uses, but I don't think that would normally prevent someone from playing.
A bug report was actually made on it a while back. No official statement has been made as of yet, but we shall see how the situation develops. https://www.sandlotminecraft.com/threads/getting-kicked.39190/ Here is the thread referring to game versions that each world is in. https://www.sandlotminecraft.com/th...s-the-sandlot-using-a-small-help-guide.35045/
