Safe-to-leave match was still counted as a loss after everyone left except one player

Match ID: 86582737

During this match, two players on the enemy lane disconnected very early. Around minute 5, the game displayed the green message that the match would not be scored / it was safe to leave.

Both teams understood this and started leaving the match. By around 5:50, only one player remained in the server. That player stayed, farmed around 23k souls, killed the Patron, and the match was later counted as a loss in my stats.

Expected result:
If the game says the match will not be scored / is safe to leave, it should not count as a win or loss and should not affect player statistics.

Actual result:
The match still appeared in my statistics as a loss.

Timeline:

  • Enemy players disconnected before/around 5 minutes.
  • Safe-to-leave / not-scored message appeared around 5 minutes.
  • Almost everyone left by around 5:50.
  • One player stayed, finished the game, and the match counted as a loss.

This seems abusable because one player can intentionally stay in a supposedly unscored match and force a win/loss result into player stats.
