The bug was fixed about a week later. There has been a dispute since then between Harmony employees and a consultant who was involved in identifying the bug, and the consultant has been accused of delaying action to profit from the excess tokens. The consultant also balked at destroying some of the tokens he mistakenly received.
The consultant claims that he didn't profit from the bug, and objected to a Harmony employee coming after him to destroy the excess tokens when he'd done little towards others who profited from the error. He did, however, say later that he had destroyed the tokens.
According to the consultant, a Harmony employee claimed that he had filed reports to the FBI and IRS about the consultant's behavior, and had the consultant banned from the annual ETH Denver event.
