Issues with message.author randomly returning undefined

[The-Lord-of-Owls]

Which package is this bug report for?

discord.js

Issue description

During the MessageDelete event message.author is for what ever reason coming back undefined and it makes no sense why a message would have no author for some, but other deleted messages still have it. It seems to be related to when the bot starts and when the message is originally sent.

Steps to reproduce:

1. Send a message
2. Start the bot
3. Delete the message
4. Code inside the MessageDelete event logs to the console the message object.author
5. Results in undefined

I see no reason why this should be happening with messages sent prior to the bot being started.

Code sample

const { TOKEN, APP_ID } = process.env
const {	Client, Events, GatewayIntentBits, Partials } = require( 'discord.js' )

const client = new Client({
	intents: [ GatewayIntentBits.Guilds,GatewayIntentBits.GuildBans,GatewayIntentBits.GuildMessages,GatewayIntentBits.GuildMessageReactions,GatewayIntentBits.MessageContent ],
	partials: [ Partials.User,Partials.Channel,Partials.Reaction,Partials.Message,Partials.GuildMember ]
})

client.on( Events.MessageDelete, async ( message ) => {
	console.log( message )
	console.log( message.author )
} )

client.login( TOKEN )

You are opting into receiving partial message data.
On MESSAGE_DELETE all we receive from Discord is the guild id (if applicable), the channel id and the message id.

If the message is not cached, there is no way to retrieve the missing data (usually Structure#fetch can be used to complete the relevant data, this request will fail, since the message is already gone when you receive the event )
