Yeah so to clarify my problem I can publish and update a (new) mod but somehow the game has unlinked the mod files from its memory of the steam workshop item so I can no longer update that specific steam workshop mod.
I checked out the page it is certainly my problem but sadly although I could publish a new version and update that one, if I deleted it on the steam workshop then I could not update (to the original mod or the new deleted one) anymore. I was wondering if anyone had the technical knowledge to know where perhaps the steam links are stored in files to the uploaded mods so perhaps I could swap it out to link to my original steam upload?
