so I made a route and I'm trying to upload it, upon hitting publish it says "no screenshot available when publishing" and once again I have no idea what to do.
I can help with this. It may give you that, and I strongly advise you take something random if possible. It is uploading it to Steam, which means you can take a screenshot and simply edit the Steam Workshop post of the scenario with that one. The in-game uploader is a bit pants, to be frank with you. When I upload my scenarios I don't even finalise the name in there, because it is easier to use Steam's interface to correct that and tag it properly and all. Let me know if that helps!
sorry for the late reply, but it appears that the problem was resolved by itself! i reinstalled the game so it could be that. but thanks for the advice anyway!
