musescore.com download PDF including parts returns "NoSuchKey" error from AWS when re-edit & re-download

I was reuploading scores and got error when try to download PDF including parts a second time after revising a score.

I think the replication steps are:

1. upload a multi-part score to musescore.com
2. on the score webpage, press "Download"->"PDF including parts"
3. go ahead and re-edit your mscz and re-upload
4. on the score webpage, press "Download"->"PDF including parts"

and then I get an error message from AWS:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<Error>
<Code>NoSuchKey</Code>
<Message>The specified key does not exist.</Message>
<Key>65943/1448986/fd30337f66/general-parts/score-parts.pdf</Key>

<HostId>p7fHngL5LIOHO6C9W6MKE9PgOz7cnJR6Un76K/bHToCQZ9NSKEY5bhXy+l84+Gj6</HostId>
</Error>

If I redit my score again and reupload, then I get a slightly different RequestID and HostID and the 2nd / of Key:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<Error>
<Code>NoSuchKey</Code>

</Error>

I suspect that upon re-upload, the musescore.com server is not updating it's database to indicate that the multi-part PDF needs to be regenerated.

I originally noticed this when I was updating https://musescore.com/ericfontainejazz/moonlight-sonata but I have been able to replicate with new scores simply by first downloading/generating the multi-part pdf, re-editing, re-uploading, and trying to re-download multi-part PDF.
