Well it depends on what your playin fallout 3 on. If its on the Xbox 360 I'm not sure what to tell you cuz I never played it on the 360, but on the pc I know that there are sooooooo many bugs for fallout 3, so if your having trouble the best website to go to is this one: fallout.wikia.com/wiki/Fallout_3 Not only will it give you an in depth guide of what to do but it does offer downloads to fix bugs. I'm not sure if they have fix for where your at, or even that it's a bug thats causing this, but this is the best place to start. Hope it helps.
