Makes sense. I didn't really see anything posted about it when I first encountered the problem yesterday but more and more people are starting to bring it up so I imagine it will get fixed pretty quickly.

It's happened to several other people I've talked to and its currently the reason I'm stuck at the end of chapter 1 and unable to progress. Even after the fight starts I'm unable to attack about 90% of the time until its too late or if I can somehow knock him off the platform. Why things like this weren't addressed in the beta I have no idea.
