I have been playing for 2 hours and the box has frozen solid 5 times. I have hit level 40 three times and the perks do not activate. Many graphical errors and map issues. When is the next patch coming (6 months), I hope it doesn't take as long as the last one. Game cannot be completed in current form. Very disappointing. Boo Bethesda and Obsidian!

Hey now, they are pretty good about patching bugs in the DLC's.
If you mean your xbox freezing, Mine does that randomly too, even before OWB so it is definitely not just tied to the DLC.
Haven't come across any leveling issues and have been playing it for atleast three hours. I like to take my time picking through each place before moving on.

Only big issue with it is not earning Caps when I sell to SCIU, other the that I have only seen minor graphical glitches randomly.

This has been more than random. My box is only 1 yr old and I have all the patches. Just struggling to get past the first time out of the sink.

I also have a new box man. One of the new Xbox slims or whatever they called.

All I was saying is that I have had freezing all over the Mojave and not just linked to one DLC and it almost always is when I am in the loading screen.
Best I can say is load a new save before OWB and try entering it again? Personally, I have only gotten frozen once in the Big MT.
