Remake withou afk(?)

I was playing as blitz, while invading we found a morgana who didnt react, in the jungle. We killed her, got first blood, i went to the bathroom (20 secs), and when i got back there was a remake vote going on which "lost": 2 yes - 3 no (i got to vote, guess those 2 where the premade in my team), and the game still ended. When i got to the score or aftermatch screen, i thought it was the other team who surrendered cause of the morgana being dc, but i was the one losing lp. after match screen
