This has been mentioned on the Nexus Forum but i thought i would place it here. When looking through the Wall Light section the game crashes to Desktop consistently, when Buffout 4 is removed the problem goes away, and i have tried old versions of Buffout and still the crash continues. I will place a bug report of Buffout 4 page with the crash logs. I will also attach the crash log here, hope it helps and I will keep people informed if a fix is found.
