Because of this error, there is a lag on my server. When the players come from the Skywars world to the Lobby world, there is a huge lag and the TPS drops and then this error is written on the console.

I fix that. This topic had nothing to do with 1.8.8 PvP, but thank you for informing me. "Set player's fly mode to false" was not supported in the script version I was using, however, it was causing lag because this error was given by the console, not the game.
