This is the second time this has happened on PC EU. I haven't seen it happen on PC NA yet.
Both times, the first match is in Vvardenfell. The second match is in Summerset. After winning the second match, I get the mail with my winnings, and the message pops up that the third match is in Gold Road. However, the quest markers are still displayed over the three NPCs' heads in Summerset, as though the match hasn't been played yet.
The first time it happened, I just went to Gold Road and the quest markers were displayed there as expected. Winning the third match advanced the daily quest as expected.
This time, I elected to play another match in Summerset to see what would happen. When I won the match, the quest markers continued to remain over the NPCs and the quest did not advance-- which I was not expecting to happen, but I wanted to see if the quest markers would go away or continue to be displayed.
I then went to Gold Road to play the last match.
The weird thing is, I think that when this happened before on PC EU, I got the same daily quest on PC NA-- that is, play the first match in Vvardenfell, then play the second match in Summerset. But what happened on PC NA was that after winning the match in Summerset, the third match was somewhere other than Gold Road-- in High Isle, I think-- and the quest markers over the Summerset NPCs went away as expected after I won the match.
I'm going to see what happens when I play ToT on PC NA later tonight.
