This morning, I opened the route in RE and added a lot of Siding names, cleaned up a bit of terrain, and added two more car-spawners.
Now, when I try to run the route in MSTS, the startup screen appears, the progress line gets about one quarter of the way across the screen and the whole thing locks up.
All other routes work OK, Conbuilder gives no errors in any rolling-stock, and a TDB rebuild in the RE completed OK.
Any ideas? I have a back-up only 4 days old, so no big deal, but it does mean setting all those signals again
Thanks.
