MCPE-1.1.5 PocketmineMP hogyan orvosoljam ezt a problémát?

Az a gond hogy amikor berakok egy 1.1.4 phart [ szerver filet ] nem generál TMP t így nem indul+ még ezzel a hibaüzenettel találkozom:[PocketMine] Server is starting...

[PocketMine] Server was started.

[Server] 10:33:36 [WARNING] Timezone could not be automatically determined. An incorrect timezone will result in incorrect timestamps on console logs. It has been set to "UTC" by default. You can change it on the php.ini file.

[Server]

[Server] Fatal error: Cannot use pocketmine\nbt\tag\Float as Float because 'Float' is a special class name in phar:///storage/emulated/0/PocketMine/PocketMine-MP.phar/src/pocketmine/Server.php on line 71

[PocketMine] Server was stopped.

Valaki Segítsen mit tegyek? :/
