Ralkage Unfortunately, I don't know. I freshly installed beta 8 and migrated my beta 7 table during the installation process. I first noticed today, after updating to beta 8.1, but I'm not sure if the issue wasn't there before.
Maybe I can just somehow trigger a recount and see if it fixes the issue?
Output of
SELECT COUNT(*)
FROM `posts`
WHERE user_id=1
matches displayed post count of user with ID 1. Closing a discussion for example is also being counted towards a users post count.
