Soooo I have a problem guys: Since today (I haven’t done anything) my game always freezes when I want to change the route in quick drive. I have no clue why this is happening but the only way to get out of the mess that it causes is to restart my pc. I tried a lot of things such as deleting an add on I bought about two days ago, but that didn’t change anything either. Also the scan made by steam for missing/broken files hasn’t changed anything. I would be really grateful if anyone could help me here :/
This is a widely documented bug introduced with the recent update caused by incompatible interlacing in thumbnail images. If it's the first page that causes it to freeze, check which nine routes are there, go into NameMyRoute, go to each of those routes and in the RouteInformation folder open image.png in Paint, then use Save As to overwrite the folder. This will fix the issue. The bug is almost exclusively caused by third party content, so to save time I'd skip DTG routes when fixing the issue.

As other people have pointed out some of the thumbnails for locos also have errors. You might find if you pick a scenario with a third party loco/unit you may have problems
Has this not been fixed with today's update? They sad they fixed the image handling. Edit: checked, the standard ThreeCountryCorner image works again.
