Sorry if I am digging up old dirt here, but I have trawled the net far and wide to see if there is a solution to this glitch, but to no avail...

I recently picked up my game again and found a quest that I didn't do during my previous run through. So, I'm currently trying to complete the "No, Not Much" quest but the game keeps on crashing whenever I approach the McCarran terminal building. I have reverted to old saves but they do not seem to make a difference. What is weird is that earlier today I was going in and out of the terminal building without any issue and this has suddenly crept in.

Does anyone have any ideas what I need to do? (short of restarting the whole game that is)

Have you saved a lot since then?

Also, when you save, do you create new files or save over existing ones?

I've heard that saving over previous saves can be bad, especialy when the file gets too big.

Sorry I can't be more helpful.

I have 3 save files on the go and overwrite the oldest each time...

So, if I try making a new save file altogether it might get rid of the bug???

Don′t do...
Always make a fresh save and delete the old one, only takes seconds.
But if you screw yourself it cost ya....

I recommend, if possible to go back an hour before the last save.
From then on NEVER overwrite your saves.
On 4 playthroughs i only had 1 single freeze at the Battle at Hoover Dam on the NCR Run.
I am using mostly 10-15 save slots for a run to be sure.

So in the end I tried removing patch 4 and it now works fine... strange.
