Reggie Jackson hit a home run while playing for the Yankees. The fans rushed the field in an attempt to mob him while he ran around the bases. He never completed his attempt to circumnavigate the bases. The league later ruled that the run did count and amended the rulebook to reflect the "fairness" principle. I doubt it was written in MLB 7.06, but it may have been written in 1976. I could be wrong about the date too.
