There are some stories on ficwad that do not download correctly (chapters are missing) in this latest version that downloaded correctly in 4.0.6.
I know this has to do to with a ficwad site bug as the chapters that don't download are numbered incorrectly in chapter list on that site but as they downloaded correctly in 4.0.6 I thought I'd bring it to your attention.
one story with a bad chapter (chapter 5) is http://www.ficwad.com/story/120853
