[BUG THREAD] The Sims 4 CAS Demo

Help! I cannot get a household to save because I'm getting the message: 

"Warning! A Family Name, Sim Name, or Description currently contains a disallowed word. You will not have the ability to later upload this Household to the Gallery. Do you want to proceed anyway?"

Two of the Sims I had saved and uploaded before: "Sam Winchester" and "Dean Winchester." The third Sim was named Castiel Angel, but I have tried changing it to "Castiel Winchester," "Placeholder Winchester," and "Safe Safe." I erased the description, although it had been allowed before. I have tried various family names, including "Supernatural," "Winchesters," and "Safe." I tried rolling the dice for name suggestions for all three sims, renaming them suggestions like "Justin Henderson," and naming the family "X" and "Safe." There are no punctuation marks or non-letter characters in any of the names.

First, if I do the "proceed anyway" to make sure I don't lose all my CAS work, will the Sims be unable to be uploaded forever, even if I later rename everything, as the warning makes it sound? I really want to save!

Second, is this a bug? None of the words seems like it could be the problem!
