During Duels I have seen different location than my opponent. It firstly loaded black screen but then I moved and clearly have seen Brasil. I went to Brasil while my opponent went for Mexico and his guess was right. After game finished I checked the recording and he has seen completely different location which was in Mexico. I see that there are some older reports of the same bug put as Solved.

It is visible in the replay. If it is worth mentioning - in previous round I was in Brasil.
