I had problems with it sticking as well. The loading screens sometimes take a long time, too. The screen normally flashes to blue when I go up to the Presidential of the Lucky 28. It can be annoying but is easily fixed if I leave.

As for your problem with Lucy I never had that happen. I have seen other areas cause the same problem, though. Mainly around Golf.

One of my files really messed up and wouldn't let me fast-travel. It just gives me a message of 'you cannot warp from this area at this time' or something. Luckily I was near the end of that file when this occurred. My main file (the one I intend to use for future DLC) has remained free of game-altering glitches.

I hope they work on a real patch that can sort all of the problems everyone is having. One of my friends didn't save for 2 hours and his file corrupted and it kicked him back to his old save.

Hyz.
