I have been reading through the forums and i didn't see anyone mention the problem i was having (although there are so many i cant read every single post). For some reason, i can't go into vault 21 without the game freezing. I loaded the game up multiple times with the problem not going away, and i loaded from an older save point and am still having the problem. I can't tell if i am having any specific quest problems other than with the brotherhood of steel quest line. I am not "venting," and i do not expect any sort of replies from anyone on this subject. I am simply posting so that developers can acknowledge the issue with my particular game freeze and add it to the list if they have not done so already. To reiterate, game freezes immediately when i try to go through the door that actually takes you into vault 21, no load screen. i apologize if someone did report this incident already.
