I am not sure why it is giving you that error. We had a problem with another site I own Gaming on Batteries but resolved it after a weekend of work (still on some bad lists that are slow to update).
You are missing a little bit because not all the staff of RGM, or GoB (or Gravis Ludus, another site I own) are archiving their content here on Steemit. I am, and have espoused the benefits of doing so to the rest of the team but unfortunately, not all have heeded the call.
