Question

Will this mod kick user when disconnects due to lag? I'm using EasyAuth (I know that mod is not yours, so i reported the issue to NikitaCartes) to let users to log, but when disconnects when player loses internet, it says "User leave the game" in log, and when connects, it says "user is already online".

Will this mod work for this issue?

Here's the log: https://mclo.gs/ouJrZl3

No I don't think the mod will help with your issue. Unless you somehow kill the lagging players with a command block. But thanks for the interest!
