So I was trying to trade a Wartortle for a friend's Heracross. After a while of Internet being stupid, we finally managed to get into the menu, we started the trade and Internet got stupid again, crashing our games with the "Communication Error, hold down Power to turn off the console".
When when loaded our saves, it turned out I kept the Wartortle, but his Heracross got "overwritten" by my Wartortle, more or less creating a clone.
We tried again with other Pokémon, purposefully disabling wireless communications during the trades, but nothing exciting happened.
One more experiment? We tried turning off the power during the trade, but no results either.
So. Since this could lead to some kind of cloning, how about some of you experiment a bit more on that?
To anyone willing to experiment more on this, good luck!
