While testing re-enabled Score (T257066), I noticed that some pages presented to not-logged in users show rendering from time period when Score was disabled, eg.:
https://pl.wikisource.org/wiki/Sieroty,_moje_sieroty

The behaviour occurs despite the pages purges/nulledits performed by a logged-in user.

Is this intentional behaviour?
If so, how to detect / avoid this discrepancy?
