hey. i don't actually speedrun this game or not but i'm not sure if this is a known bug or not?

i was playing the game as usual, cleared out the graffiti for the skyscraper district, then went back to the center. the immortals appeared, and a tagger's tag started.

played like i normally would, tagging the backs, but the AI was...odd. they were bumping into things and not exactly being quick. i figured nothing of it, and just kept spraying.

however, like maybe 10-20 seconds later, i won. i didn't even take anyone down. it just said i won and they were at highway zero.

what happened? did i accidentally find a skip? is this a well-known skip/bug?

tl;dr did the skyscraper tagger's tag vs. immortals and i just won for almost no reason in a very short amount of time

someone inform me i am a confused young bab
