Because it's simply unplayable it's current state. I fear I may have to put the game aside for a while until it's fixed, much to my own disappointment, especially having JUST bought the new DLC. The only fix I've found is restarting the system, but that's only VERY temporary. Anyone have any fixes? Or are we all just out of luck til they decide to fix it? I know this isn't just an isolated thing, I've read on other sites about people having this very same issue.

I roam around the Mojave for 20 minutes, then get the bug, rinse, repeat. This bug has been present on every DLC so far, and even flows over into the non DLC parts of the game. I was so happy when I bought it earlier today. Been looking forward and dying to play it ever since I first found out that they were making it. What makes it even more maddening, is that I just bought the Lonesome Road DLC today.

I can't even make any progress in the game because of this. But most (99%) of the time, you have to completely restart the ps3. Sometimes you can get lucky and quit out of the game that way. And pressing the PS button to completely exit the game is the same way, have to press it over and over until it finally responds. If you try to save, it takes about 2 and a half minutes to fully save to 100%. Then it slowly fades into the start menu. It IS possible to pause the game, but you have to press start over and over and over again, until the game finally realizes you've been pressing it. Moving, shooting, pausing the game, everything, slowed down to a crawl. This of course renders the game completely unplayable. While I'm playing, the game will randomly start slowing down, the frame rate dropping constantly, down to the point where it's literally like 1 frame per second. I love Fallout, and normally I can forgive little bugs and whatnot, but this, this is TOO MUCH.
