I think I had a similar experience!
I noticed some ground coverings missing in my favorite route. There were grid lines showing along the tracks so I got out of the route and opened the content manager and there were a lot of faulty, missing and open for edit items.
I spent most ot yesterday trying to resolve as many problems as I could and tonight I saw that that route looked normal.
When I started the game before seeing the problems, one of those automatic searches for missing assets started.
I have questions:
Why doesn't the automatic search resolve the missing asset problem or isn't it worth the code it is written on?
How do assets come up open for edit? I didn't to it! Do people upload assets that are open ????
How does a route look good one day and is missing scenery the next? It isn't like I was making changes to the route, I was just driving it!
Thanks
