[Crash] could not remake even though 1 player was afk since min 0:00

Hi guys. Today on a ranked and naturally on a my Promo. A player was afk since min 0:00. We thought its gonna be a remake so we chilled and played till min 3:00. The problem is we couldnt remake and had no clue why we couldnt. Evelynn(the player who was afk) was in the center of the fountain and did not connect or buy items.

this is the game https://matchhistory.euw.leagueoflegends.com/en/#match-details/EUW1/4064752188/36714814?tab=overview

My question is now: is this a bug? or did we something wrong?

If it is a bug: Riot fix it pls

sincerely Schmoggy
