So, I haven't battled in a couple weeks now and something odd happened.
I went on Fartsie's stats page and it displays 74 wins, which is impossible. I vividly remember having over 200+ won battles and probably something near 90 loses as well as a couple of ties. I remember something about a reset(?) but what in the world happened to my actual stats. It looks like I've never battled in my life and yet I have over 60k exp pts to spend ?
Most of my Morostide, plots and special opponents results vanished. I don't remember such thing being an actual "news" of Subeta.
There was a reset recently, it not only resets wins so you can re-battle opponents but it clears all your win/loss stats.
There was an opponent reset when the battledome revamp occurred, in May.

My stats are the same. I have 90 wins total, which is a fraction of what I had prior to May, and all the stats for the old opponents I battled have also vanished. On the up side, you can go re-earn all the battledome prizes again, and we did see the Gargoyle opponents back this summer, so maybe they're going to reintroduce the retired opponents in some fashion in the future.
