The issue is being tracked here: https://phabricator.wikimedia.org/T249477
A fix has been deployed but may not take effect on all affected wikis
before the end of the run. In that case we will run manual no-op jobs on
these wikis to fix up the symlinks and the index.html files.

Thanks for this report!
This bug must have been introduced in my recent updates to file listing
methods.
The multistream file is produced and available for download by changing the
file name in the download url.
I'll have a look Monday to see about fixing up the index.html output
generation.
