Ah, well that would be it, I hit 'Yes' to all the overwrite prompts.
Anyone else have experience with the aforementioned sound-loop bug upon exiting the game? Basically it acts as if the game crashed when I close it properly. Well, no error messages or anything but I always used to get that annoying sound loop when I had to CTRL-ALT-DELETE out of F3 or FNV due to a glitch or freeze.
Also, random question I thought of reading through the forums here. Are there currently any restrictions in place as to traveling to NV from DC? I've just been roaming around in the F3 world so far, I should probably test out NV sometime though just to make sure that works well too.
