i had the same issue not long ago, but it not a ae issue, you can't any support in here.

optfine and forge has some compatibility problems, someone use optfore mod to fix it.

I can in theory see how this happens. Do you by chance have a slow network connection?

Reproduced by forcefully slowing down GUI syncs between server->client.

This is a race-condition and should happen rarely. Will look into fixing this.
