17:07:17.292 [JDA [1 / 2] MainWS-ReadThread] [ERROR] n.d.j.core.requests.WebSocketClient - Completed the setup for Guild: G:SNIP(SNIP) without matching id in Ready Handler cache

Got this error on 3.3.1_286 , while booting up shards.
There is no other log or stack trace to indicate the reason, just a bunch of these in the debuglog right before that:

Is this consistent and reproducible?

[schnapster]

Don't think so, didn't get that during a restart yesterday. I'll try booting (a copy) of the bot up and down a few times to try and reproduce and also check whether the guild that caused this is still present, and report back.

[schnapster]

Guild is not present anymore. No luck with a bunch of starts, didn't get any errors.

[schnapster]

Just happened again after a reconnect (running JDA build is hotfix-zlib branch).

Debug log has those same Caching Presence lines (about a hundred per shard reconnecting) as shown in the OP, didn't see any other suspicious things.

[MinnDevelopment]

Is that consistent on shard 0?

[schnapster]

I have only observed these two incidents, might be chance.
One thing to note is that I cache some guild data on guild join, and this guild is not in the database, which means the GuildJoin event was missed (probably happened during the reconnect).

[MinnDevelopment]

I think I know what's happening:

1. Disconnect
2. Connect
3. READY -> stores guild ids to build
4. GUILD_CREATEs for those guild ids
5. GUILD_CREATE for new joined guild, no matching id -> error to console

Edit: Cannot reproduce

[MinnDevelopment]

Does this still happen on 48bc751?

[schnapster]

Yes still does (on 305). Got two of these in the aftermath of the discord outage earlier.
