  bot.addChatPattern("guild_left", /^Guild > ([\w\d]{2,17}).*? left.*$/i, {parse: true})
  bot.addChatPattern("guild_member_left", /^(\[.*?\])*.*? ([\w\d]{2,17}).*? left the Guild!*$/i, {parse: true})

That bot.addChatPattern exists on the bot property in the version 4.9 and above as changelog does not state that it had been removed.

This is because you are not waiting for the correct event. mineflayer requires you to wait for events like spawn before those functions become available.

Worked before without waiting for that event, so it was defently not mentioned in the changelog

It should not have been working if it did, as createBot() is not a synchronous call, it works asynchronously. As in the examples, all the mineflayer bot API methods (like this one) have to be called after the appropriate event, like connection to server, etc. Should be made clear in the API if not already. Feel free to do a PR to add that note to the api.md
