On the final step of the Vulcan's Hammer side quest, 'Returning the blueprint to the scientist in Roseway' upon entering the room with the scientist the game crashes to desktop. I've tried saving and loading to try again, sprinting in to start a conversation as quickly as possible, looking out of the room and even tried ignoring it and doing other quest to come back to it later but still ends in crashing. I'm not sure what else to try to fix it or even it can be fixed at the moment, any help would be appreciated.
