In my last match i win because my opponent doesn't fill enough players, and it's right but why the player take different mins from that match?
4 of my players play 36 while 1 46 mins...and the 2 opponents players take 43 mins...is it a bug?
This is not a bug.
Players are assigned minutes based on their positions in the game chart (36 for starters, 10 for backups, 2 for reserves, I believe).
Additionally, you can't get 48 minutes in a walkover by fielding a player as starter, backup and reserve at the same time.
