Upon the release of the season 11 battle pass, a handful of new cosmetic voice lines were added that all share a bug in common—you can hear them across the map. The voice lines were taken down relatively quickly and made unavailable until a fix was ready. And so that fix “happened.” But it didn’t actually work; earlier today I was able to hear a Kiriko using her new voice line across the map during a skirmish. Additionally, I tested the rein and doom voice lines and the enemy said they were able to hear them from their base.
“This isn’t even my THIRD most final form!” - rein
Oh, so that’s what that was…
