Average Price Today, on hover, is definitely not displaying Average Price Today. It seems to be an average over the past few days.

This is probably easiest to see in the news; any of the stuff released this week doesn't have an Average Price Overall and the Token Shop stuff is all being shown as having purchases today.

Maybe has something to do with the pet hunger issue? I might be pulling straws, but this has been going on for a few days (I've been suspicious, but couldn't think of a way to prove it) and both are site-related time-bound issues. Maybe not!
