I think I have narrowed this bug down to punctuation problem in the description or name. When I repeatedly got the message that the puzzle had a parsing problem and saved it with no name or descri[ption I tried again with no punctuation and removed commas, periods, dashes and apostrophes. My guess is its all of them but most likely apostrophes that is causing the problem.
This has been reported before, a few times, but never fixed, and has gone on for years (literally).
If you use a comma or an apostrophe in the title or description of a solution, it uploads to the server as "No Name" and can't be downloaded by anyone else.
Small annoying thing - but we all make the mistake sometimes, and teams need to spend time with new people explaining the bug over & over again.
It would be great if it could be fixed…
Seth, this is a silly bug, hopefully it's a quick fix.
Looks like is fixed. Closing.
