It is correct that the administration decided on 19:45 GMT for your match, unfortunately at that point we had forgotten about the time change on Sunday. We corrected that mistake 30 minutes later when we made announcements in the announcement thread and all match threads. Considering it was still Thursday, I thought that all teams would read about it, speak to their opponents and adjust accordingly. Still, the fault is on my side. I should have made sure with both teams over Steam, considering there had already been issues agreeing on a time for your match.
Therefore, my apologies that the match couldn't happen. Because there are no prizes associated with the final standings in Division C, we won't make a decision on this match. Should you wish to do so, you can still play your match until Tuesday evening.
