I still wish they give everyone the ability to erase puzzle panels they don't want and/or like, (but able to re-download them if they change their minds).

There's no reason to delete a puzzle.

And the new puzzle isn't available yet (at least to me it isn't).

Why delete the puzzle? Doesn't that just cheat someone who streetpasses you out of getting puzzle pieces? :(

If you could erase a panel, it would make it easier and quicker to use Play Coins to get pieces for panels you want to complete. That's the only thing I can think of.

I'd suggest maybe a "hide" feature that removes them from view in the Plaza, but is still there and available for people to collect pieces from. :cool;

Do you have to do something specific to get this puzzle? I haven't seen hide nor hair of it.

Still haven't seen this myself. Maybe streetpass is broken.
