After I activate the purifier and the ending clip is done, I just lay there on the floor of the Jefferson memorial. No 2 weeks later or anything, and I don't know what could cause this, are there any mods that could have affected this? Such as MZC or the hair pack or Street lights? Those are the only esms I have that I can think of that might have cause this?

Load order?
If you use a custom race, you need http://www.fallout3nexus.com/downloads/file.php?id=6240 to get through into Broken Steel.

Ok I'll give it a try.

Edit: it works! Thank you very much!
