If the internet connection of one player is lost, he will lose one game of the match. The reason for this decision is preventing the players from cheating or manipulating the game. That means the player loses the whole match in the qualification phase and in the group stage. If the internet connection of the TRC-Team is lost both players continue their match until they will reach their goal. Both players continue streaming on their own Twitch-channel independent of the official stream. The results are valid and determine the winner. There is no repetition.
Only the best 128 players can advance to the second part of the qualification phase where the live matches are played. The qualification table is decisive. That means if a run is evaluated with the criteria and your seed is 129 or higher, you won't be advancing to the second part of the qualification phase.
