By the end, the Panda team had prepared a follow-up report on the instant lottery errors and crappy back-up issues that we reported earlier this year.

In September last year, an instant lottery error occurred that did not match the visual win and the systemic winning, and at that time, the government lottery commission and the trustee Donghai Kwon quietly recovered 200,000 instant lottery tickets that were believed to be erroneous, hiding them from consumers.

Two months later, when some people raised the issue, they belatedly stated that they had completed action on the error in three days.

By the end of last month, a single 500 million won first-place lottery ticket had not been completed, and questions remain.

By the end, the panda team first looked back at how the East Happiness Circle managed to sift through 200,000 copies so quickly.

This is the contents of a Telegram chat room of East Happiness Circle officials on September 7, 2021, the day after the lottery error was confirmed obtained by SBS.

At half-past eight in the morning, the fact of the discovery of the lottery error is first disseminated.

Just 1 hour and 40 minutes later, the message 'No missing verification number' appears.

Here, the verification number is the serial number assigned to confirm the winning, which can only be seen after scratching the instant lottery ticket.

It's different from the number that is exposed at the bottom from the beginning for lottery ticket circulation.

The absence of a missing verification number means that there is no missing serial number, that is, when the damaged winning data was compared to something else, the lottery and the lottery authority said that they compared the backup winning data that was left in the lottery printing house at the time with the damaged data.

'No missing verification number' The next message was 'Total 180,090 sheets of inconsistency'.

It seems to imply that the number of ranks has changed from 180,090 sheets, just below, "It was the original 0th, 2 1st, 2nd, 2719... You can look at it this way.'

If you look closely at the table, it is marked as if the existing 0th place, i.e., 2 cards were changed to 1st place, 2 cards were changed to 2nd place, conversely, 2 cards were changed to quack, and 2 cards were changed to 2nd place where the existing 2nd place was changed to quack.

I even checked to see if the number of ranks had changed, and it seems that there were two first prizes in them, but when I asked if this was an analysis of the 200,000 copies that were recovered at the time, he said that he was not sure at first, but recently he gave an unexpected explanation.

[Lottery Commission official: If it's printed, it's A, the PTMS (corrupted winning data) is B, and now the backup data is C. A, B, and C were all different.]

As it turned out, even that backup winning data had been compromised.

There was a difference between the two whether the time or degree of damage was different, and since the damage was compared with each other, the first prize 2 and the second place 2 pieces mean nothing, and after that, I again specified the 200,000 pieces to be recovered through the process of scratching them one by one, but I don't know if there was a first prize in them.

[Nam Gung-heon/Print Lottery Club Manager: I drove after drinking, but it's not drunk driving. I opened it, but I didn't see the first place. It's ridiculous, this is.]

As a result, there was no proper flawless winning data anywhere at the time, the lottery commission said.

Still, the lottery quietly sold the remaining 25 million tickets, two-thirds of the total, and 25 billion won worth of lottery tickets.
