There is a real problem with the CentralAuth extension, and especially with the "global oversight" feature.
I noticed in the past that sometimes oversighting an account globally won't remove stuff in the logs on local wikis (mainly newusers, deletion and block log). I noticed that when restoring a global account, the entries that were previously oversighted by CentralAuth are not restored.
But I've never seen things like that. Now, when you oversight an account, it is not removed from [[Special:ListUsers]].
If you want to know exactly the users I'm speaking about, please contact me privately.
That's really something critical, so I think that something should be done to fix the multiple issues with this extension as soon as possible. Thanks by advance.
