Issue #22335: UFO Crash site possible NavMesh issues, launching NPCs into the air, followers avoid crater
UFO Crash site with a follower / companion of the two legged human variety, experienced odd behaviour of companion
In the following screenshot I have llamaRCA's new companion Heather ( http://www.nexusmods.com/fallout4/mods/23273/?
) in company. She avoids the "bowl" of the crater which is just before where the ship is (behind me in the screenshot)
And occasionally when she sandboxes away to the other side of the crater bowl, she will launch into the air and then drop back to earth, possible navmesh issue ..
.. I am guessing that after the crash maybe the game is supposed to set a new navmesh for the changed landscape, and its a bit buggy.
