There were not 3 official accusations of dice issues. Only one. The others were just offhand comments that added up later. But it was made officially to a TO and needed to be addressed like any other "judge!" call during the event.
I would say as a bit of unsolicited advice. Unless that one person had something to back up the claim then player 1 should of never been asked to swap out dice.
Just because someone accuses someone else of something doesn't mean a TO has to take action, not without something to back it up.
I'm not saying the TO did something wrong mind you, just saying how I would of dealt with it... But I wasn't there, and a lot of nuances are missed that way.
