A small note with competitive consequences

The August 20 hotfix contains one targeted gameplay fix: Mizuki can no longer access unintended locations on certain maps. Blizzard did not list balance changes alongside it.

Out-of-bounds positions can create sightlines, invulnerability pockets or rotation options the map was never designed to support. Closing them quickly protects both ranked play and organized competition.

No replay-code reset was announced

Because this was a server-side hotfix rather than a full client patch, Blizzard did not announce a general replay-code reset. Players do not need to download a large update to receive the fix.

The note is brief, but it closes one of the stranger edge cases discovered during the first full week of Season 4.
