I was wandering does it interfere Broken Steel or any quest that has to do with The Outcast?

Don't think so, to me it just looks like it makes changes to the fort itself and not anything to do with the actual outcasts

Should be safe to use. If not just de-activate the ESP file no harm done

Ok, Thanks for the reply Stafare wanted to make sure before I downloaded it.
