Now a couple of weeks ago I posted this: https://forums.dovetailgames.com/threads/failed-to-publish-file-on-steam-workshop.92961/ Having done further investigation I worked out that the reason this was happening was because of the screenshot. As a test I uploaded the scenario with a random screenshot from an older scenario I had and sure enough it worked. Later on I tried uploading a different scenario on a different route with a different, more recently taken screenshot and it failed to upload. Now, having tried with different screenshots from different dates it seems that every Trainsim screenshot taken on my laptop after about a month ago is faulty and doesn't allow me to upload to Steam Workshop, but every screenshot before that point does. Has something gone wrong with my laptop or is it something wrong with TS Classic?
