Only Mistake In The Olympic Opening Ceremony?

In what has been said was a nice Opening Ceremony at the 2014 Winter Olympics in Sochi, it seems this light malfunction it the only big blunder that occured.

It seems that five smaller lights were to expand to the Olympic symbol but it didn't happen and the picture you see was the end result.

I am sure the 'nit pickers' will find a bunch of things that went wrong but to the normal people, if this is all that anyone could really notice, it wasn't that bad.
