Fitzyhere just posted a clip to Reddit featuring a bug with Sombra that shows that if a teammate has detected Sombra, she becomes visible to other players on that team who are outside of her detection radius. This change was not listed in the patch notes.
I’m pasting a link, but if it’s gone it’s visible in FitzyHere’s Twitch clips and in the SombraMains subreddit and his Twitter(X).
