katos Not quite sure what you mean with this one sorry? Please can you provide steps to re-produce?
Since you are an admin you can view the post's that I have deleted. So if you look at my profile (while signed in) you'll see a lot of posts including some deleted in between.
But then if you log out and look at my profile like any other non-admin user you will see that the posts shown are only till the last post I deleted, everything after that is missing.
An even better example:
If you look at the profile of @hrvoje_hr (while logged out of Discuss). You'll see his profile has only 5 posts (But post count is 120). Now if you look at his profile while logged in you'll see there is a post after the 5th post but it is deleted (temporarily... You can see this because you are an admin). So the posts that are displyon a profile are only till the last post the user deleted.
