Anyone know if the second guard to be found in the main crypt is supposed to be missing? Or is this a bug?

I found them all... One was dead.

I have the strategy guide and I see where the second one is supposed to be, and I figured he was in a sarcaphogus or one of the piles of bones but nothing registers. I have found the other two without a problem.

Nope. All of them were pretty plain to see. Either tied up or in the middle of the floor dead.

Sounds like a bug...
