Mystery of the Broken Temple - tip [spoilers]

There's a place near the end of this quest that it looks like you can't continue. Spoiler for tip.

You have to destroy 5 orbs with the rod. The last orb, center front, is available. But the hit box is small and weird. Just wander around the alter until you find it, it's there. You don't have to find another rubble pile or anything. I found it about 2 body lengths back from the alter in the center.
