Is Q&A official?

594 questions and counting... a tough task for any set of refs to memorize.

So long as the 'bump' didn't slow the climbing robot down, cause it to fall, or otherwise cause grief to its team I'm not sure there's a reason to call the bump consequential for this case. However, it would set a very dangerous precedent for referee calls if some teams realize that they can intentionally 'bump' the pyramid on the way by while a climb is happening. In retrospect, the ref probably made the best long-term decision without realizing it even though the interpretation of 'consequential' is in question.
