当我试图提交一道团队内部题目的时候，页面弹出了一个错误提示框，内容为：

Argument 2 passed to Luogu\Manager\ProblemManager::hasTag() must be an instance of Luogu\Model\Tag\Tag, null given, called in /app/luogu-web/source/src/Library/Judge/Judger/NormalJudger.php on line 122

我查看了一下提交记录，发现多出来了一个提交记录：https://www.luogu.com.cn/record/161075184。状态为“Waiting”，但是连续等了三分钟都没有结果。期间，页面提示我“提交过于频繁，请3分钟后重试”。

三分钟之后，我再次尝试提交，出现了同样的错误提示和同样的评测结果：https://www.luogu.com.cn/record/161075407

使用 F12开发者工具 的“网络”选项查看请求结果为：

{
    "status": 418,
    "data": "Argument 2 passed to Luogu\\Manager\\ProblemManager::hasTag() must be an instance of Luogu\\Model\\Tag\\Tag, null given, called in \/app\/luogu-web\/source\/src\/Library\/Judge\/Judger\/NormalJudger.php on line 122",
    "errorMessage": "Argument 2 passed to Luogu\\Manager\\ProblemManager::hasTag() must be an instance of Luogu\\Model\\Tag\\Tag, null given, called in \/app\/luogu-web\/source\/src\/Library\/Judge\/Judger\/NormalJudger.php on line 122",
    "trace": "",
    "customData": []
}

希望管理员尽快修复，谢谢！
