You guys were right; it's loading the default map. I renamed my test map but now I am receiving:
FATAL ERROR
FATAL ERROR: Could not load world file 'custom_stories/Test Story/maps/main/ch01/00_test_rainy_hall.map'
My user_settings.cfg has:
<Map File="00_test_rainy_hall.map" Folder="custom_stories/Test Story/maps/main/ch01/" StartPos="" />
I tried using an absolute path:
<Map File="00_test_rainy_hall.map" Folder="C:\Program Files (x86)\Steam\SteamApps\common\Amnesia The Dark Descent\custom_stories\Test Story\maps\main\ch01\" StartPos="" />
And that didn't work.
