If a route on the DLS gets updated, and one has already made an extensive session based on that route complete with AI, then the updated route won't have the session and one must start from scratch with the new route. I think I read that there is a way to edit the session one has created, and change the kuid numbers in that session to point to the revised route ( provided there aren't major changes to the revised route) What I need to know is what exactly what has to be changed, I think there are two places that the kuid has to be updated, but not sure which two. Thanks.
