I am unable to publish updates to one of my designs in the workshop. It looks like Steam has forgotten that I am the creator. I am signed onto Steam and subscribed to the blueprint. I have the subdirectory with "__<blueprint number>" in the Blueprints directory, but in the F2 blueprint menu I do not have the entry with the little icon that shows I am the creator. So I can spawn it from the workshop, but I can't publish updates to the workshop. I have cleared the Cache directory, validated the game files, and started a new Creative-mode game. I don't know if this is related to the bug report from May, but it looks like something different. Is there anything I can do? It is not that big of a deal, but I hate to delete the item from the workshop and start over if I can avoid it.
What worked for me was to copy the .ebp file from the subscription directory to the __<blueprint number> creator directory. Of course I lost all my unpublished changes, but at least Empyrion / Steam realizes that I am the creator of my own design again. The body is one. "Thanks, Landru!" "You're welcome, Landru!"
