Panzer: The AI has a tricky ability, which I think is fair enough. If *someone else* in his group can see you, but he can't, the other guy will tell him "hey, he's in those bushes!" and then he will unload on you without being able to directly see you. That's probably what happened. I think they really have fixed the foliage view issues.
