I noticed in the changelog it said it fixed these 2 issues:
"Fixed rare issue where dragons would not attack"
"Fixed rare issue with dragons not properly giving souls after death"
I had previously had 2 Dragons that I could not get to attack me but I never had the soul issue, until the 1.2 patch.
I was doing the misc. bounty quest where you have to kill a dragon at Bonestrewn Crest, when I got there it would not attack, and it was flying very erratically. That included getting stuck, moving up and down very fast, even flying backwards! I eventually managed to kill it, only to not absorb it's soul... I'm not complaining just wanted to bring to light the issues still exist, and the is the first real bug I have come across.
