1. Does this happen when you've shot out the glass? It's what I always do when I expect company
But it could be a game engine limitation you've stumbled on there.
2. It's another game limitation issue, but I might be able to circumvent it. As it is now, the Smugglers are friends with Miguel, and since Miguel is part of your team you'll inherit that friendship. That's why the guards started shooting at you when the smugglers threw nades at them.
The issue with the enemy knowing where you are, and in this case Miguel especially, is one of the weaker points of the AI. If just one of the enemies sees you, they all know where you are. And in the Miguel case, he's their friend and they then know exactly where he is. But I might be able to fix it by removing that friendship, but then the previous missions might get screwed up. I'll have to check this out a bit and see what can be done.
Don't you just love this game? It's when it's the most challenging and frustrating that you get your biggest kicks. Well, at least when you overcome them
