There is one scenario I am trying to upload which still won't, I have tried with another scenario to see if it was a problem with just the individual scenario or Steam Workshop as a whole and the other one worked. I have checked to see if the issue is 3rd party content but it can't be because it says Ready to Publish. Yet I still get the Failed to Publish File message. I have changed the scenario screenshot, and made sure it is the correct file size but that doesn't do anything.
Have you used anything from the Steam Marketplace? I'm pretty sure I read somewhere that they cause a scenario to be rejected.
I think when it says Ready to Publish it is being checked and if it finds a problem then you get Failed to Publish.
Not necessarily because if you use third party routes/rolling stock it will tell you in that box that it can't publish.
I can't remember but I have used items from Steam Marketplace in scenarios before and I was still able to upload them onto the workshop.
I did not say you were using third party rolling stock. I said it is finding a problem. Only you know what you have used in the scenario Do you have any repaints in the scenario?
Try uploading it without that reskin and just the default loco You would then prove that it is or not the problem.
I didn't do that but I tried uploading it with a screenshot from a different scenario (and then deleted it from the workshop) and that worked. It showed the screenshot was the problem not the reskin, the problem is now finding a screenshot from that scenario that will let me upload it.
Well surely if it uploaded with a different screenshot from a different scenario then it would mean the screenshot was the main issue not the reskin.
