Fallout 3 is one of my favorite games of all time, but unfortunately, Fallout 3 has glitches and bugs, like when the game freezes, but I've found that there are more glitch's in the second expansion pack, The Pitt. But there is one that annoys me so much. I only needed to get 4 steel ingots to get the achievement, and i have to walk across a roof up by the WildMan base were you get 10 steel ingots up very high after climbing up their structure, well whenever i try to walk over it, i fall right through the roof like I'm same sort of magician, and i eventually just gave up on getting those last 4 ingots. Post something if you have encounter the same or any glitches with The Pitt.
