Hi I get a server crash whenever I generate a world and then teleport to it.

here is the error message: [20:02:43] [RakLibServer thread/CRITICAL]: TypeError: "Argument 1 passed to pocketmine\utils\Binary::writeLTriad() must be of the type int, null given, called in phar:///home/minecraft/pocketmine.phar/vendor/pocketmine/raklib/src/protocol/EncapsulatedPacket.php on line 163" (EXCEPTION) in "vendor/pocketmine/binaryutils/src/Binary" at line 248
then after that:
