Re: War Table Bug - Timed Missions

To the west of Orlais, there should be a region marker for the Western Approach, with the fade indicator above it. If I remember correctly you don't actually enter straight into Here Lies the Abyss, you'll need to find Adamant Fortress first. 

Here's an image of the war table location. Ignore the extra clutter, I only had a later-game save to use.
