@white: AFAIK, it doesn't, sadly. Drop rate apparently only affects the chance of regular enemies dropping something, it does not affect phantoms which are already guaranteed to drop something, nor does it increase the chance of a rare drop.
I've been playing the game alongside Brad, hoping to get the platinum. The Pure Bladestone it a real show stopper though. Still, I'll probably try farming it for a bit when I get to that point... Who knows, maybe I'll get lucky.
It seems as if the number on the Images tab (on game pages at least) counts every image added since the code merge twice. If you look at new games added since then with a single default image, they all list 2 instead on the correct 1. And when I added a single image to the Sly Collection page, it went from 14 to 16.
It seems like locked threads are showing the creator of a thread in the Last Post field on the Recent Topic view instead of the person who actually made the last post. It's most apparent in the Delete & Combine forum, given how requests there are locked once they've been handled.
