With the QuestionableQuesting XenForo2 update and forced relog, any attempt to download a QQ story is met with "HTTP Error in FFF '400 Client Error: Bad Request for url:

I've double checked the saved username/password in personal.ini, made sure I'm up-to-date, and tried downloading a multitude of threads from around the site, no dice.
Just read back, noticed the qq test update, will try that.
Yep, works. Turns out the only problem was my lack of reading comprehension. Thanks!
