Sometimes it fills all the cannons but with different boards, from time to time pieces will get stuck or it will mess up, or abandon station when all of the cannons aren't filled. Also something I noticed is sometimes it glitches out and i have to restart the bot. My main concern is the pieces getting stuck, if the people who made the bot could update it so pieces won't get stuck, make it load faster and not mess up the cannon that would be great. Otherwise it has gotten me to respected which is great.
