if you dont get this, in the opening ceremony there were 5 giant oval lights that started as dots, then they opened up to form the olympic rings, but the top right one was broke and just stayed as a dot.
also, in the version they showed on tv in russia, they cut this out and added in the practice run where it worked correctly, although you could see the stands were empty.
this is what it looked like in real life, except with browser icons added
