I've been working on the same task and I do not have "No Bane, No Gain" in my completed list, nor have I seen it available from the levemete. Also, I burned through 20 allowances the other day trying to get "We Didn't Start the Fire" and it never showed up in the list so I am thinking it is not in the game. There are a few others like this that I am questioning if they exist at all in the current version. Here is my list of outstanding leves:

Central Shroud
Lv. 1 - "No Bane, No Gain" - Muriaule / The Bannock
Lv. 5 - "We Didn't Start The Fire" - Muriaule / The Bannock
Lv. 10 - "Mite and Madness" - Tierney / Bentbranch Meadows
Lv. 10 - "Hog Wild" - Tierney / Bentbranch Meadows
Lv. 10 - "Too Close to Home" - Tierney / Bentbranch Meadows

Western Thanalan
Lv. 10 - "What Peistes Crave" - Totonowa / Horizon

I know this section of the forums probably does not get much traffic but any information of these leves would be greatly appreciated!
