Forum:Steel Ingot bug (not the roof)

I collected all the ingots but one, but I don't feel like going through and finding the last one, because I just wanted the gun. Anyway, Everett won't talk to me and won't come into the mill. He just stays in the abandoned area and when I try to talk to him his lips move but says nothing at all. Has anyone come up with a fix for this bug on how to complete this?

This happened before doing the main quest of The Pitt, so I went through and finished the quest and that didn't help the situation either.
