The story of the Great Oscars Best Picture Gaffe of 2017 keeps getting more juicy.

After Warren Beatty was handed the wrong card and wrongly announced that La La Land, not Moonlight, had won Best Picture, the Oscars did an investigation and found that a partner from PricewaterhouseCoopers, which handles the envelopes, handed Beatty the wrong card.

The employee might have gotten the cards mixed up because he was distracted. He tweeted a picture of Best Actress winner Emma Stone backstage right before Beatty’s announcement.

Now, a source tells PEOPLE Magazine that Brian Cullinan, the partner who mixed up the envelopes, wasn’t supposed to tweet, out of fear something like this might happen.

“Brian was asked not to tweet or use social media during the show,” a source tells PEOPLE. “He was fine to tweet before he arrived at the red carpet but once he was under the auspices of the Oscar night job, that was to be his only focus.”

The source continued, “Tweeting right before the Best Picture category was announced was not something that should have happened.”

Quite the series of compounding mistakes.
