Do you have to hold every single long note for its full duration? I remember getting the full combo medal for 3 star mania just by missing 0 times, even though it wasn't the highest combo possible. Unless I've gone insane and I made this memory up, shouldn't this be the same for 4 star levels as well? I have 0 misses on a few 4 star beatmaps, and just a few combo off of the max amount, and I still haven't gotten the breakthrough medal. Whats going on here?
