Simple Hybrid Cannon - an important reminder

The schem that I sent you had a mistake (an extra piece of redstone dust that causes the cannon to not work properly). I did point this out but no idea if it got addressed. If it would be easiest for me to send the fixed schem, please let me know This may or may not have already been taken care of, but bringing this up as I don't know if the blueprints will have to be remade (some of them in /shop are the wrong schems and don't work, separate reports)
