The update should hopefully be out this weekend! I've added so many new features! I'm super excited for the release. I'll probably be dropping some clues on the next update on the thread. You can follow the thread to make sure you're up to date with all the news!
Also, the rule about leaving three slots open is to ensure that you will never get stuck. Such as if you try starting the bot with no room in inventory when you need to be picking up more than one item. It's just a safety feature. But you don't have to worry about losing traps, this script will collect all your traps before logging out!
