There are currently only 15 barn finds in the game. There is an achievement for getting all 15 barn finds. That means the tracker should go up 6.66% per barn find.
It was working fine, until I did two barn finds at the same time. Now the tracker is 6.66% behind what it should be. For example 9/15 should be 60% but for me it is 53%. This means it is now currently impossible for me to get the achievement.
I know many other people with the same problem.
I’m sorry if this has already been reported, but I checked on the known issue list and through a couple of pages of posts.
