Professional League of Legends competition faced significant disruption during the 2021 LPL Summer Split when EDward Gaming clashed with Bilibili Gaming. The decisive third match encountered an unprecedented technical issue that halted gameplay for over sixty minutes.
Initially anticipated as a brief interruption, the pause extended dramatically due to a critical Sett interaction bug. Standard chrono break procedures proved ineffective, compelling tournament officials to authorize a full match restart. Despite the extended delay, EDG demonstrated remarkable consistency by securing victory in the replayed encounter.
The problematic interaction involves Sett’s ultimate ability Show Stopper (R) targeting opponents actively channeling Hexflash. This specific sequence triggers a permanent summoner spell deactivation that persists throughout the entire match duration.
When Sett executes his Show Stopper against a champion preparing Hexflash, the targeted player loses access to one summoner spell permanently. This game-breaking mechanic gained attention hours before the professional incident through content creator documentation.
EDG support specialist Tian “Meiko” Ye became the professional victim when his Flash summoner spell became permanently unavailable after diving against BLG’s Sett player Yu “Biubiu” Lei-Xin. The irreversible nature of this bug creates competitive integrity concerns at all gameplay levels.
Following the bot lane engagement, EDG immediately requested a competitive pause. Tournament referees determined the bug’s severity warranted extraordinary measures, culminating in a complete match reset.
The critical incident occurred at the eleven-minute mark while EDG had established a substantial early-game advantage. The team successfully replicated their strategic performance in the restarted match, ultimately claiming series victory.
This disruptive bug had already gained notoriety within the League community through popular YouTuber Vandiril’s detailed analysis. His technical breakdown demonstrated the exact reproduction conditions hours before the professional match incident.
The LPL competition operated on patch 11.11, confirming the bug persisted through multiple weekly update cycles. With patch 11.12 deployment underway, competitive and casual players alike anticipated immediate resolution.
Should this critical bug remain unresolved, consequences extend beyond professional competition to affect millions of solo queue participants. Losing primary summoner spells like Flash creates insurmountable disadvantages, particularly during crucial late-game team fights and objective contests.
Professional players must maintain awareness of known bugs when selecting champions and abilities.
