I'm experiencing a very strange behavior. When entering the area of the workshop at the airport, or fast travel to Robco Sales, East City Downs, East Boston Prep School, Or exit from the Mechanists Lair the game instantly CTD.

I found this while working on Liberty Reprimed quest for Proctor Ingram, I'm on the part to build the 4 actuators. When leaving the platform to head to the workshop area, just as I pass the bus the game CTD. So it seems to me to be a cell bug. It also seems to be Automaton DLC related. If I remove the DLC esm and load the same save the problem does not occur.

I have sort of found another workaround but I'd like to figure out what precisely is causing it so I don't have to use the workaround every time I'm at the airport or near any of the other spots. I found that if I'm wearing power armor the crash doesn't happen. If I exit the power armor while in the problem area it instantly CTD.

This isn't a solution but I do believe this might have to do with the Automatron DLC, I didnt go with the BoS, infact you'll find the Prydwens wreck there, but thats besides the point, I didnt have this issue until I had beaten the DLC and was about to exit, only for it to crash.
TL;DR I think its the Automatron DLC, regardless of plot paths.

Hi I can add to the fact that I think the automatron DLC is causing some crash, I don't know if my game will crash at the airport but like patriotickevin I can't get out of the building after the end of the automatron DLC.

Its a bug caused by Automatron. Mechanist Lair's map icon bugs it for some reason. I found a fix for it and it worked

@Fiddller Thank you very much for the heads up. I didn't recall that I updated my DEF_INV with DEF_UI which also included DEF_HUD. I don't personally use that so I removed it and it solved it for me, though I understand some people have the problem with vanilla hud too.
