Thankfully you can go back with the undo arrow and then go into Story mode and write whatever the HECK you wanted, or edit what the bot is saying.
Often the bot screws up my stories with something ridiculous or sends me to sleep or kills me out of nowhere. It introduces guns when I'm in a fantasy setting or magic when I'm in a realistic setting.
Also use /remember and add in the notes of the world. Like to which character you been talking to or important information about the world, where is a place located, whats the climate, who is the ruler of that place, all the faction information etc.
