Inaccurate data on user statistics
 

I've seen multiple users where I found their profile thorugh a certain post and then, looking at their posts via the profile, the post I just looked at isn't there (usually the latest post shown is just an older one) and there's just a significant chunk missing between what the overview says (the one on the top right), and what's actually shown when I look at their posts via search or vie the link in their profile. I tried deleting cookies because I thought it might be a browser issue, but that definitely resolve it. Is this a site issue?
