Discord.js: presenceUpdate event - old and new presences are always identical

[FluxMonkii]

Both old and new presences always appear to be identical.

bot.on('presenceUpdate', (oldMember, newMember) => {
  console.log('old:');
  console.log(oldMember.user.presence);
  console.log('new:');
  console.log(newMember.user.presence);
});

gives this:

You need oldMember.presence, not oldMember.user.presence
