Bumble Bee successfully (and regularly) detects the new versions of extensions, e.g.
https://wikiapiary.com/w/index.php?title=Absurdopedia%2FExtensions&type=revision&diff=4718388&oldid=4715821
... but "This extension is in use on the following websites:" on the extension page is not updated for weeks.
For example, https://wikiapiary.com/wiki/Extension:Moderation still believes that Absurdopedia uses Moderation v1.2.52 (it started using 1.2.53 on 6 June 2018).
