Does anybody understand how this ended?

It must be a bug. Please check the error. no one to resign. The game crashed and got lose match at my team when we were ahead

Silent_AI I agree with you that the game was not won at all, mine was just a feeling based on the possession of the map.
But what I was interested in, was pointing out the seriousness of the BUG that needs to be examined carefully. You can't throw away an hour of play for nothing.
The serious fact is that the PROGRAMME HAS ARBITRARILY ESTABLISHED THE WINNER, no one knows by what criteria.
This could affect any other match.
In cases of crashes it gives both teams the game lost.
In this case to me it appeared while I was playing suddenly the reward screen without any writing at the top neither defeat nor victory.
I think it is worth reporting this to the programmers, not because of the game itself, but because it is a serious precedent.
