Adobe Illustrator: Inexplicable Transparency
I want to work on an SVG-File I downloaded from here: http://commons.wikimedia.org/wiki/File:Risk_board.svg
I opened it in Illustrator and removed everything but the strokes. But there's a problem, there is some inexplicable transparency on the lines. Opacity is set to 100%, Blending Mode is "Normal", but see for yourself:
Can you help me remove this effect?
Edit: Selected a line in the screenshot and here's a dropbox link to the actual file I'm working on: https://www.dropbox.com/s/y3hghnja22t0wkg/risk_map_001.ai?dl=0
Use the Direct Selection Tool (the white arrow) to select a path, then just look at the Appearance Panel.
