The two teams battled it out on Sunday, but the match was placed under review after it became apparent that a bug involving Puck's Phase Shift and its interactions with various forms of disable had affected the game. Today, the administration of the Brawl released their official ruling. After determining that the bug did have a significant effect on the outcome of the match, DotaReplays has awarded the victory, and the first spot in the Final Four, to Natural 9.
Since Fire were not warned during the match, they will not face punishment and will be given the #1 seed in the second qualifier, which will take place on January 22.
And since, without the shadow of a doubt, with confirmation from Icefrog, a bug was occurring that aided the survivability of Puck, and this bug occurred multiple times and had at least a moderate impact in the game, our final ruling is this:
Because of the use of a potentially game altering bug, regardless of malicious intention, we've nullified the match and awarded the first slot in the Final Four to N9. Team FIRE is not banned from participating in future qualifiers and instead will be first seed in the next qualifier happening on the 22nd of January.
In addition, DotaReplays has clarified and expanded their rules regarding bugs and reporting them to the admins:
To prevent future abuse, deliberate or accidental, the admins have banned Puck from use in future tournaments.
