MuseScore file not available for Old Online file

I'm having problems accessing one of my old online scores.

This is the score in question
https://musescore.com/user/1837341/scores/2152021

When I try to open it from the MuseScore client I get this error:
"Your score could not be opened
The score could not be found, or cannot be accessed by your account."

When I try to download the MuseScore file from the web interface I receive the following:

NoSuchKey

musescore.scoredata
tx000005f47ea04578b5b21-00685a50a4-2ac4c65-default
2ac4c65-default-default

I am able to download as PDF, XML and MIDI though.

I don't have a local copy of this file. Obviously I can rebuild it from MusicXML or the PDF, but I'd like to recover it if I can.
