I'm not sure if that's true in the first place. There is no way such development can take place on that much short period. If that has to be true then there would have been movement in the forum itself.

Or that could be about the mega exchanger that was hacked recently and theft steal away 580 million NEM coins. This means that transaction over that exchangers are completely halted for the time being and this appended up the transaction which were halted for long time.

That's just presumptions but story and logic can be different really.
