What is the Remedy When Tipoff is in Wrong Direction.?

[xyrph]

I was at two separate games this week where the officials started the Tipoff in the wrong direction and at each game about twenty seconds in they stopped the game and instructed players which way to go and continued on with the game without doing another tipoff... instead inbounding from the sidelines.

Neither game had scored any points yet, but I am really curious what happens in this situation when there are goals scored before they realize the error.

To be clear, the referee throwing the ball up for the tipoff instructed the teams to go the wrong way... in both of these games.

How is this supposed to be fixed? Should the game be restarted?
