Apparently it's the Demon and LIch campaign's that are most affected. Owlcat hasn't been clear on how to determine if your save game has issues. I'm personally losing about 7-8 hours of gameplay if I have to back (having respecced on Sunday), though I'm playing an Angel so I might just risk it. Make sure you do not respec for now.
For once my horrid case of restartitis works in my favor!
