ZOMG Gnome General Doesn't Work On Normal

[Black Boo 3]

So a friend and I teamed up and decided to face the gnome General. Unfortunately when we did we got beat since it was just two of us on Hard Mode. No Biggee, respawn and set it down a difficulty to Normal. When we did and entered we encountered....a bug. After all his gnomes the general didn't attack, at all. Nor could we attack him. Eventually we just left the boss area which as far as I know shouldn't have been possible anyway.

I use Internet Explorer, and Windows 8. But the glitch itself happened for both of us so I'm not sure what had went wrong.

Yeah, GM is broken on normal. :c
