Hmm... Apprently the latest episode isn't 100% filler but omake based (though I wouldn't have remembered).

The Fairy Tail Wikia seems to possess quite a respectable listing of the eps, with canon, omake, and filler marked very nicely. I guess I should have a look at this latest ep, then. I haven't been watching Fairy Tail for a long time, not since the long filler arc launched. As I keep reading the manga, such a pause isn't so bad for me.
