Not sure if this is a bug or I'm just doing something wrong, but whenever I create a team with a mega evolution on Pokemon Showdown for OU beta it tells me my team was rejected because the mega evolution cannot use the ability it gets from mega evolving. This happens with all mega evolutions, not just Charizard-Y as shown in the pictures. I've spent some time trying to figure out what's wrong but I haven't seen any forum posts from people with the same issue. I've tried both the desktop client and the online client but it's present in both.
