According to Giantbomb, Warrior’s Lair has an alias of Ruin (it was the working title of the game) hence the confusion: http://www.giantbomb.com/warriors-lair/3030-35560/
Assuming this is your game http://www.giantbomb.com/ruin/3030-48419/ it is currently listed as a stub so it will not be included in the directory. Once that is updated to a full article and Twitch imports the new data it might fix the issue.
