Actually, could I just reinstall a route and then submit edits?
I'm not sure if that will help because reinstalling the route will not download the dependencies again because in Trainz, routes and other assets reference the dependencies internally and through the config.txt file. For routes, this is an internally through the route data-files, however other assets such as a locomotive will reference dependencies such as interiors within the config.txt file.
What are the dependencies that are missing, or what is wrong with them?
To list the missing dependencies, right-click on the route and choose List dependencies. A new window will open up and whatever is used will show up there.
On the columns, right-click and add status; it'll load on the far right. Click on it and slide it to the left.
Click on it to sort the status show that anything that's missing shows dashes and the name will show unknown asset.
I highly recommend adding all the columns because that will help you sort and search a lot easier.
Highlight the missing assets.
Press CTRL+C to copy the data
Click on a new post in Missing Kuids and paste it there. We can then help you find the missing parts.
For faulty assets, right-click on one at a time and choose View Errors and warnings. A window will open up showing the errrors. Highlight the text in the window and paste it here. We can assist you with repairing the assets.
