Hi.
Lastnight i installed the beta patch and go to the Faneuil Hall, to do two missions (Rescue a citizen and The Gilded Grasshopper) i didn't have any problem to do the missions, i entered to the building completed the Rescue and then go to the roof to take the gilded grasshopper but when the missions ask for "Go to the somebody grave" I left the building and turn to the right and the game crashed.
So i load another save and then turn to the left and go to the market location and the game didn't crashed. I attached a image to explain better the crashed zone:

the blue square is the place to go, the red circle the zone that crashed and the green circle the safe zone that didn't crashed
