(*Session).State is broken in all versions after 0.20.3

[NaniteFactory]

I've been using discordgo for months, and these state caches became all empty since release of v0.21.1.

session.State.Guilds
session.State.Channels
session.State.Guilds.Members

Can someone take a look into this please? Thanks.

Are you using intents? If so, what intents are you requesting?

[NaniteFactory]

Well... I'm not aware of whether I'm using intents or not, because none of my codes explicitly request any intent.
Below is how I get my session connect to Discord. I guess this may be somehow relatable?

// Open shards sessions and add event handlers to them.
func (d *Discord) Open(handlers ...interface{}) error {
	d.mu.Lock()
	defer d.mu.Unlock()
	// Get Gateway Bot.
	gateway, err := discordgo.New("Bot " + d.botToken)
	if err != nil {
		return err
	}
	st, err := gateway.GatewayBot()
	if err != nil {
		return err
	}
	// Shard into sessions.
	d.shards = make([]*discordgo.Session, st.Shards)
	for i := 0; i < st.Shards; i++ {
		d.shards[i], err = discordgo.New("Bot " + d.botToken)
		if err != nil {
			return err
		}
		d.shards[i].ShardID = i
		d.shards[i].ShardCount = st.Shards
		d.shards[i].StateEnabled = true // just in case
	}
	// Add handlers.
	for _, sess := range d.shards {
		for _, handler := range handlers {
			sess.AddHandler(handler)
		}
	}
	var errOpen error
	{ // Open ws connections.
		wg := sync.WaitGroup{}
		for _, sess := range d.shards {
			wg.Add(1)
			go func(sess *discordgo.Session) {
				if err := sess.Open(); err != nil {
					errOpen = err
				}
				sess.StateEnabled = true // just in case
				wg.Done()
			}(sess)
		}
		wg.Wait()
	}
	// Close if fail.
	if errOpen != nil {
		wg := sync.WaitGroup{}
		for _, sess := range d.shards {
			wg.Add(1)
			go func(sess *discordgo.Session) {
				_ = sess.Close()
				wg.Done()
			}(sess)
		}
		wg.Wait()
	}
	return errOpen
}

It's expected that this code will not work for fetching and caching members. This was described in the release notes for v0.21, as well as the FAQ.

[NaniteFactory]

Okay, so I went to https://discord.com/developers/applications/ , ticked both Presence Intent and Server Members Intent, and just added this line of code.

sess.Identify.Intents = discordgo.MakeIntent(discordgo.IntentsAllWithoutPrivileged | discordgo.IntentsGuildPresences | discordgo.IntentsGuildMembers)

And it's working again as usual in the lastest current master.
sess.State.Channels and sess.State.Guilds are just fine. I might have mistaken those for something else.
Sorry for my ignorance and thanks a lot!! @CarsonHoffman
