Since the automatic export for MediaWiki core/extension some exports removed newly added message documation in qqq.json:
Another case, the otherway;
For the first case, the messages had been added many hours earlier: https://gerrit.wikimedia.org/r/c/mediawiki/core/+/1008552. When did you process the message changes?
In the logs I see

Change 1009519 had a related patch set uploaded (by Nikerabbit; author: Nikerabbit):
[mediawiki/extensions/Translate@master] Add debug logging to GroupSynchronizationCache
We had a pair debugging session with Abijeet. We found a probably cause related to interaction of ImportExternalMessageChangesMaintenanceScript and ExternalMessageSourceStateImporter when the --safe-import parameter is not used.

The fixes for this have been deployed on translatewiki.net. Exports and imports are working as expected. There is no direct way to test this. We just shouldn't see this issue happening again.
@Raymond Please let us know if you still see this happening.
