我制作了一个不和谐的自定义游戏。它从scramble-words.json文件中的单词列表中抓取单词并对其进行加扰。这些单词会被放入文本聊天中，玩游戏的用户必须尝试找到实际单词。它会删除自你开始游戏以来发送的所有新消息，并在游戏处于活动状态时保持频道清洁。你必须键入这个词，如果它是正确的，你就得了一分。
第一次运行命令时，代码运行良好。第二次出现错误UnhandledPromiseRejectionWarning: DiscordAPIError: Unknown Message和您在新游戏中发送的每一条消息。
我试着查找它是否需要我将games = {}变量指定为常量，但我不认为这是问题所在，我想不出它还能是什么。

删除消息，然后尝试获取该消息，或在方法中使用该消息时，会出现未知消息错误。我可以在您的代码中看到2个message#delete方法，这些方法几乎总是导致这些错误的原因。仔细查看代码，找到要删除消息的位置，并确保之后没有使用任何与该消息有关的内容。这里的帖子显示了这些错误是如何发生的。
我可以看出这个错误会引发的一个原因，如果你在游戏中迭代，你在第一个游戏中使用message#delete，程序运行良好，然后在所有其他迭代中，它会引发这个错误。这是因为message#delete正在尝试删除已删除的消息(即，当您在第一个游戏中第一次删除它时)。
