Bug Cancelled Clash on Some Servers - Riot Fixes Before Europe
An unknown bug cancelled Saturday Clash tournaments on Eastern Hemisphere servers including Japan, Vietnam, and Korea. Riot identified the problem and is fixing it before European matches start on EUW and EUNE servers.

What Happened to Clash Tournament This Weekend
This Saturday's Clash tournament was supposed to run normally on all League of Legends world servers, but a technical bug disrupted plans for thousands of players. The problem specifically manifested during second games in the tournament, forcing Riot Games to take drastic action.
Why specifically the second games? This tournament phase is critical because it determines advancement to the elimination bracket, so any error has a devastating impact on the entire tournament.
Eastern Hemisphere servers were most affected, meaning tournament cancellations for hundreds of thousands of players in these regions.
Which Servers Were Affected 🌏
Cancelled Clash Tournaments
✓ Japan - Complete cancellation of Saturday matches
✓ Vietnam - All planned tournaments stopped
✓ Taiwan - Players unable to finish started matches
✓ Korea - One of the largest regions without Clash weekend
✓ Oceania - Australian and New Zealand players also affected
❌ A common mistake is underestimating the impact of these outages - for many players, Clash is the main team activity of the week.
Riot's Quick Response Thanks to Time Zones ⏰
The time difference between Eastern Hemisphere and Europe proved advantageous this time. While it was already Saturday evening in Asia, European tournaments weren't scheduled to start for several hours.
Repair Timeline
- Saturday morning - First problem reports from Asia
- Saturday afternoon - Riot identifies main cause
- Saturday evening - Fix deployment for European servers
