I am still listed as last logged in 4 months ago. Maybe they are in the process of updating but not done yet.
Actually, that is kind of odd. When I make the first click from here on my username it showed four months ago but when I fully clicked into it, it shows today. Odd that the initial view is different.
Same with yours. One click on the username here still shows 4 months ago but when I actually go through to your profile it shows today. Nice photo.
