Forum:Strange freeze in tents outside Lincoln Memorial

So sometime after finishing the "Head of State" quest, I entered one of the newly placed tents outside of Lincoln Memorial. After walking around for a few seconds in the tent, the game froze (it wasn't a computer-locking freeze; I was able to ctrl+alt+del my way out of it). Curious, I entered the game again and went in another tent in the same location, and the same thing happened. I get an occasional freeze or crash here or there, but never one that seems to be location-based. Anyone know of a fix for this? I have the 1.7 patch installed.
