- Go into Content Manager.
- Search for the route.
- Right-click on the route.
- Choose View Dependencies.
A new window will open up.
- Sort by status by clicking on that *column
The unknown assets will be listed together.
- Highlight the missing assets by clicking on one and moving your mouse down to select those.
- Press CTRL and the letter C at the same time to copy the list.
- Paste the list here in this thread and someone can help you find the missing trains by pressing CTRL and the letter V at the same time.
If you don't see that column, right-click on the columns and add status from the list. You can then drag and rearrange the columns to suit. I recommend adding them all and resizing them to fit your screen.
