There is a possibility that it is incorrect, but it seems that this problem does not occur if the following character string is set to something other than "Spectator". https://github.com/pmmp/PocketMine-MP/blob/ccc76cf33852fad3e0cca8ab805b8b15cd503f76/src/pocketmine/Server.php#L491 https://github.com/pmmp/PocketMine-MP/blob/ccc76cf33852fad3e0cca8ab805b8b15cd503f76/src/pocketmine/Server.php#L482-L492 May be involved. https://github.com/pmmp/PocketMine-MP/blob/74bef7f4237dfaf5d80af2d0a493944ade1fd068/src/pocketmine/network/mcpe/RakLibInterface.php#L205-L215
