What kind of match was that? The playoffs have begun in League of Legends: It will be decided who will be champion in the regions and who will go to the Worlds.

In the Korean leagues, two strong teams met in the quarterfinals on August 18:

• DAMWON Gaming (who sold their name to KIA) are the reigning Worlds runners-up. In 2020, they even won the Worlds. The team has two of the best players in the world in midlane and jungle with Showmaker and Canyon. This year, top laner Nuguri is also back, although he has since lost his regular spot. They finished fourth in the league.
• They met the fifth of the LCK, KT Rolster, who are always just behind the top teams in South Korea like T1, Gen G. and Damwon KIA.

Player loses upgraded item when he returns another one

What was that bug? The bug occurred about 30 minutes into Match 2 of the “Best of Three” competition. KT Rolster has released a statement, e-sports journalist Ashley Kang has translated it (via twitter):

We would like to make a statement about the break in game 2:

The pause was requested when the ADC Aiming on Kalista bought a Stopwatch and then returned it, this reset the Ornn upgrade on Immortal Shieldbow.

So a completely bizarre bug, but one that put KT Rolster at a significant disadvantage:

• Top laner Orrn had boosted an item of ADC Kallista by his special skill
• Kallista bought a stopwatch and gave it back again
• This made the Ornn upgrade on the other item disappear

This put the team at a disadvantage. KT Rolster requested the break in hopes that Riot Games would chronobreak the game back so that they could continue playing before the bug occurred.

How did Riot Games decide that? Riot Games investigated the incident during a 42-minute break, but then decided not to reset the game via chronobreak because the incident “was not previously detected.”

Team that suffered disadvantage due to the bug lost the game and eventually the series

This is how it continued: DWG Kia was able to win the match, which had been even before.

DWG KIA took a 2-0 lead in the series, but KT Rolster came back to 2-2 and a reverse sweep was in the air. But once again, KT Rolster proved unlucky.

What else stood out? As former Korean pro Wolf noticed, commentating on the game in Korea, there was a second bug in the same game. The bug allowed KT Rolster’s ADC to use his flash even though he was actually enchanted by Ahri.
