Championship - Type B Anything Goes Winter Seasonal - Round 1

For anyone using mega Rayquaza, currently pokemon showdown is not giving you the option to mega evolve rayquaza in an AG battle. It happened to me in my tournament battle and it's happening to people in the AG chat room. In case your asking too, I was using Dragon Dance, Draco Meteor, Dragon Ascent, and V create as my moves along with a life orb and still the option to mega evolve did not come up. I think this is a bug in showdown considering others are having the same problem too.
