Purchased the expansion yesterday and loaded it up and the AI is horrible. They no longer respond to sounds when you throw a bottle, they also walk through doors. I was staring into a building in the first level wondering where the guard went, shrugged went owe must have walked through the door or whatever. 20 minutes later (I'm on the hardest difficulty and going for no one seeing me) he walks back through the door and I'm like owe, I guess he did walk through the door.

None of the guards will even check out an area if they see me. They just get a notice sign over their heads and remain in place like they have no investigation mechanic anymore.

Anyone else getting these bugs?

I haven't noticed anything like that. My guards come to investigate almost immediately if they ge tthe red alert.

What's the problem with them going through doors? Do they glitch through closed door or something? Otherwise I don't see the problem.

I can't even play the 2nd area of the 2nd mission. My game crashes every time I enter it, or I'll be able to enter it, but the game never finishes saving, no one talks, there's no sound, the textures are muddy or completely nonexistant, and the game crashes if I open up my journal or pause menu.

I put a topic in the hardware/software issues forum, but I haven't had any response.

Makes the initial release of "The Pitt" DLC for Fallout 3 look playable.

When fighting Guards with blade, dodge animation wont kick in so my blade just passes through thin air, meanwhile there still taking aim and bullets are tearing me a new one.
