So i have my main save with at least two days worth of time, and i wanted to go back to sanctuary to build as i like the layout for having a road and all. So when attempting to build or so much as flip a switch, the game crashes. At first thought i thought it might have been homemaker or something similar, so i disabled them but to no avail it didn't help. I reloaded a save hours before then, it helped for maybe all but two minutes before crashing again. My latest attempt had me disable the AI which also only bought me some time before crashing again. Someone stated in another posted i looked up that it had something to do with the engine Fallout 4 uses, but i am not sure. Is there any way to fix this without having to start all over or risk it happening again?
