I was trading with another player to help him evolve his Poliwhirl with a Kingsrock. I accepted and received the pokemon but declined to evolve so they can do it when I trade back. On my screen, the pokemon had to rock on them but when trying to trade, the rock was not there so they declined. I tried to move the pokemon to a different spot and it disappeared. I checked my /pc but the pokemon was not anywhere. Just wanted to post about this so it is known. ~LordPanda_
