I have no proof of this glitch because I know replays wouldn't have recorded it, but I was playing Challenge Cup 1 VS 1 and it for some reason made me pick the order for all 6 of my Pokémon. If I recall correctly, they were: Zoroark, Crustle, Hydreigon, Abra?, Ludicolo, and Klink. I assume that Zoroark being first (or being there at all) is the reason behind this, but I am not certain. Either way, I was confused, and I'm sure that anyone else would be too if they had this happen.
Also, in another battle in Challenge Cup 1 VS 1, Spit Up did no damage after Stockpile, but still got rid of the Def/SpD increases (it left the Stockpilex3 though, which is wrong). Replay: http://www.pokemonshowdown.com/repla...cup1vs18475510
