I have a problem with PocketMoney and SignShop plugins. That's what I get in console when my brother tries to get stone sword from the sign for free. Code: 12:53:16 [CRITICAL] Could not pass event pocketmine\event\player\PlayerInteractEvent to SignShop v0.9.2: Argument 2 passed to PocketMoney\event\MoneyUpdateEvent::__construct() must be an instance of pocketmine\Player, null given, called in phar:///home/ec2-user/PocketMine-MP/plugins/PocketMoney_v3.2.1.phar/src/PocketMoney/PocketMoney.php on line 192 and defined on SignShop\EventListener\PlayerTouchEvent 12:53:16 [NOTICE] InvalidArgumentException: "Argument 2 passed to PocketMoney\event\MoneyUpdateEvent::__construct() must be an instance of pocketmine\Player, null given, called in phar:///home/ec2-user/PocketMine-MP/plugins/PocketMoney_v3.2.1.phar/src/PocketMoney/PocketMoney.php on line 192 and defined" (E_RECOVERABLE_ERROR) in "/PocketMoney_v3.2.1.phar/src/PocketMoney/event/MoneyUpdateEvent" at line 29 HOW TO SOLVE THIS?!
