I did a little poking around the first page and didn't see anything that seemed to correspond with my problem; if I missed the topic, sorry. I'm feeling pretty sick right now, and so I'm not really in the mood to do hardcore searching through the forum.
I first noticed this with my own latest submission, but, after doing a little poking around, it seems as though it's occuring with most of the more recent submissions. The view page of these submissions seems to be frozen at a point not long after the submission; from what I can tell, around an hour or less; and nothing on these pages seems to be updating, even though notifs of their change in real time are still being posted. As an example, my latest wallpaper was submitted around 15 or 16 hours ago, and it's still showing as having been submitted 1 hour, 3 minutes ago. The number of views and downloads hasn't changed on the page since last night, despite having checked in on it a few times since then, myself; and the number of favorites is marked as 0, though I've received notifs for two favorites since then. I've tried viewing my wallpaper, and some of the others that I've noticed with the same problem, in multiple very solid, high-performing browsers, and I get the same result.
I can't speak for any other submitters, but the only thing that I can think of that I may have done that may have influenced this is that, right around the time that it became frozen, I updated the wallpaper--I'd originally forgotten to put credit in the wallpaper itself, and so I uploaded the corrected version around an hour after I had originally loaded it. Though when I click on the thumbnail, the updated wallpaper appears no matter what the browser, in some browsers the thumbnail appears updated, while in others it doesn't.
Just to let you know, I've only checked the recent submissions in anime wallpapers, and no other category. Here is the link to my wallpaper's view page (http://gallery.minitokyo.net/view/253644/) and the two other wallpapers that I've checked so far (http://gallery.minitokyo.net/view/253756/) (http://gallery.minitokyo.net/view/253744/).
