+2 passive points from Alva gone forever?

After completing act 3 and going to Kingsmarch I skipped through the dialogue with Alva as per usual and ended up clicking past the skill point book. No problem I thought, I'll just talk to her again to get it, but no, she just walked off and vanished. Tried going back to act 3 to talk to her but nothing. This feels like a gutpunch of an oversight. Is there no way for me to get those skill points now? Is my character essentially bricked??
