You can just stop the craft at any point if you really need to type something, and then “start” it up again afterwards. Miqo will just pick it up where you left it, no problem.
It messes with your crafting counter though if you’re crafting more than 1 of something.
But yeah, since Miqo isn’t telling the game “use this ability now” via hax but instead tells the game “hi. me, the user, is pressing the button ‘3’ right now”, you can’t chat while miqo is pressing buttons, or you’d just write the bot’s keypresses into chat.
