I (and Wobby) have had similar issues with the LC ladder. We both had high rankings (him being #1 and me being #11) but now it's saying we have lost over 200 matches since last night despite us not playing at all.
Most likely what happened is that you misclicked on something else when you meant to click on Bullet Punch, or lag accidentally registered the wrong move as being clicked.
If it was the lag thing, I have plans to fix that, don't worry.
The current UU ladder is for the suspect test; i.e. Snover with Snow Warning is unbanned.

The foe's B00 had its energy drained!

Zekrom used twice Fusion Bolt on a Chinchou that had Volt Absorb. Twice, the damage is not absorbed.
I still won the battle, but that seriously hindered me...
I was battling a Golurk and it used substitute, my Vileplume's effect spore still took effect though. I'm pretty sure that's not supposed to happen...
