Mission 3!

It's here! Mission 3! And my theory was partially correct! Only, there's one problem: At the very end it is hard as usual! When you have to match the symbols, the second line of squares won't flip over when click on them! I don't if it's just a bug, or if the web site just wants to laugh in everybody's faces and say, "Ha! Ha! You're too stupid!" It makes me feel bad that I can't open a safe of my own branch! If you've solved the safe, please comment and let me know!
