xbox360pcps3 There is a metal box that is difficult to reach due to a invisible wall next to the cliff wall, and even if you somehow get around the invisible wall (traveling around the cliff and thus around the wall), the metal box is empty anyway. If you go into third-person and look at the box at an angle it is possible to reach, however stated previously it is empty. If you use fast travel you may be stuck behind this wall, impossible to get out of there.
ps3 Sometimes a deathclaw may be next to the makeshift beds and completely ignores the player and the Great Khans.
if a deathclaw follows you to the encampment on your way up, it will spawn there every time you fast travel there even if you killed it.the khans cannot kill the deathclaw so they will almost always be killed by it, failing the quests.this will happen even after clearing out the quarry.
pc When climbing the nearby rocks, you may fall into them. At that point you must load a previous save, as you can't fast travel or jump in that position.
