I was playing as Ambassador Faelin and came in second place but the victory sceen said that I got 1st. I also unlocked the achievement for coming first with Ambassador Faelin but when I go to my stats it correctly shows that I was second.
This can all be seen in Screenshots below.
There were 3 players left, the other 2 played against each other and I played against a ghost. I was knocked out by the ghost at the same time as 3rd place was knocked out. This displayed correctly on the scoreboard bar at the left of the screen.
