SP2 installed just fine. That's the good. The ugly is that EVERY layout that I have done has multiple errors now. The ugly is this: the first route that I tried to see if it would run, had a missing loco. Not visible. A green arrow appears where the loco used to be, but it isn't there. Trying to place a different loco there leaves an empty space between the newly placed loco and the first car of the rest of the train. This sucks big time. I have run several extended data base repairs, I have done the Content -> update with more extended DB repairs and still have the same issue. Please help. This layout was my latest and greatest with 150 bases and everything just about perfect. Now this.
