The Gnome in the vent near the last door is an error to me and other people. We played on this map a lot around a year ago and the gnome wasn't an error but since we decided to get on the map again today, we seem to recognize that the gnome is an error for all of us. When we were playing on the map before, we didn't have Half-Life or left for dead mounted and we still seen the gnome but now we don't. It's just a error.
