Or are the rules still being figured out? Also, i don't see a platform option for series s

There's currently a bug with Legends where every once in a while, there will be a popup saying "Connection to the server has been lost." Usually, all it does is block the screen from being broadcast while the popup is up. I've had a few IL runs be rejected because of this, but what happens if it were to occur in the middle of a full story run? Would I need to return to the lobby and restart the level, or would the full run be invalidated due to me restarting a level?
