Rule 19: A unfinished game dispute must not stop the gaming session:
If during a gaming session played without neutral host (always considering two necessary games conform a match) results in a game interrupted by a OOS, a crash of any kind, or a DC where players don't agree about reporting it, the match shall be re-played on the same host anyways. The unfinished game shall be, later, posted as a AR.
If the AR is approved, the subsequent rematch played on the opposite host will be necessary to conform a match. Thus, one of the players gains the right to play one game on his own host.
