Yeah I cannot enter the area to try and fix the issue. I would have to do it remotely. I was hoping perhaps there may be a console command like 'scrapall' that I could use with a cell name "scrapall CellName' for example.
Sorry I was unclear.
Before the patch and after the behavior is the same. An earlier save does not (one taken while I was building on County Crossing) and a save taken later at The Castle crashes when I fast travel, walk, or use the console command 'coc' to enter the area of the area around County Crossing.
I was stacking two windmills, wiring them up, then left to work on The Castle.
My recollection isn't perfect, it was a couple days ago, but I don't think I did anything like work on quests or anything. My quest list looks to be the same, so I am not sure it is quest related.
