Don't worry about Scout. That is the way to unlock the story episodes. You move automatically through the maps after finishing a live or a battle. People don't notice it since they just skip the result screen.
After finishing all the Episodes, you get a Free scout map with 777 steps. You get some items and 7th coins for completing it and then you immediately start a new one.
Since the Scout screen is useless once you complete everything, something that takes less than a month, it makes sense for it to be removed.>Is this game going into near EOS or something?
People have been saying that for seven years and the game is still running. Also, they are releasing a big update in August for the 7.5 Anniversary, so I don't think they would bother to do that if they plan to shut the game down.
