Appeals Committee. Disputed situations in tournaments.

Today, I played a match against Logistic as part of the selection for FB 7. Around turn 117, my opponent said that a message appeared stating that his hero had already been released and he didn't receive the hero. He then left the game. I request that the admins investigate. I am ready to provide the save files.
P.S. We were playing in SOD (Shades of Darkness).
