I had posted my problem with TRS19+ earlier, but now I cannot find it to edit. So here it is again. After opening a route that I had build in an earlier version, and after making some changes, I save the route and then I exit out of surveyor. Trainz completely shuts down and leaves the route open for edit. When restarting TRS19 it has to do a re-build of the database. Then I have to make sure that nothing is open for edit before I can work on a route.
