Thanks, that's a bit easier for me to understand. I agree with JT, 32 points.
The advanced rules for the Labyrinth say translated: "In addition, for each Meeple in the maze, you score 2 points"
I take 'in addition' to mean, after the points for the road have been scored:
Total = Road Score + Meeple Score = (Road tiles x2 for German Cathedral) + (5 Meeple x2).
Edit: Similarly, the German Castles give +3 points to a road, AFTER the road has be multiplied by 2, when a German Cathedral is present.
