I can no longer get Hiravias to cast Returning Storm or Relentless Storm.  The icon shows above his head for a second, but then he just goes back to regular combat.  Meanwhile, he can cast all of his other spells (at least the ones I've tried).  I don't know if this started with 2.01 or before.  I was just trying to do the last two groups of bounty tasks tonight when I noticed the problem.  I hadn't had any complicated fights that needed storms for a couple days before that.  Any ideas?

 

SWC

Happened to me too.  I know there were instances before when it happened but I was able to fix it by moving or something.  I have not tried that but it was happening to me.  Post a link to your saved game through dropbox and the output log.  Instructions are on the first comment in the forum but for now since it happened to me in the Spider/Ogre cave east of Dyrford I will post it.
