After several more unfruitful tries over several days, I opened a support ticket at Dovetail Games Support. A few days later, they replied that they could not help me and told me to contact Steam. Another few days passed before Steam replied that "Steam Support does not offer technical assistance with content creation in the Workshop." Clearly, I was not asking anything related to content creation: just why my scenario, after being approved for publication, failed to publish. I've added a reply to their absolutely useless message, but without really expecting an appropriate reply.
Have any other forum members had this same problem recently? [Yes, I have tried several file verifications and cache clearings.]
