Possible Bugs
This NPC is one of the few characters which is known to randomly disappear and never be found again.(I have found him dead once lying across from the bomb) This is often the result of Stahl falling from stepping off an overhead walkway or getting stuck in the water behind the bomb and dieing of rad poisoning.
