Hey,
It appears that the Tram Conductor Animatron at Dunwarren - Central Station disappears once you leave the area and return to it (used line 7 to explore, then came back - he was gone).
Figured that like with the Rafter when someone else is using the tram the NPC is gone, but it obviously not so!
Thanks to friendly DM Winston I got out, but after 3 hours, occasionally checking if the NPC appears, it did not.
Hm, very odd - I think it might have been because someone took a tram and then didn't finish their journey. Report if this happens again...
Actually, this has happened before. My PC and some others reached central station through the core of the machine tram, left the area to explore and when we came back the tram conductor was gone. DM core ported us out in the end.
