I see:

These tools had a cache for the category tree which was used in the queries. TheDJ already talked to me that there was an expectation this would happen. The fix is probably a complete rewrite.
This is related to T142807: Migrate all users to new Wiki Replica cluster and decommission old hardware. s51362__erwin85 is on c3.labsdb, which is now readonly.
