Syntrix

I've been progressing through A bridge ablaze, enjoying the time skipping back and forth, but I think I've run into a bug, or something too obvious that I'm just not seeing. I've retrieved all three of the glowy soul fragments you find laying about, I've got the key that gets you the book that you have to give to the priest. I didn't do any of the fancy options when interacting with the Godhammer, just tried to force the soul fragment out. The bomb went off and I was automatically teleported to Dusk, but I never actually received the 4th soul fragment. When I go back and reuse the bomb, it says I already received the soul fragment. When I go to Waidwen he says he's still not complete. I'm at a bit of a loss and the last save file I have before this happened is about 5 hours of gameplay ago. Anyone have any bright ideas? Save file attached as dropbox link, since it's too big for me to attach the file to this post. https://www.dropbox.com/s/3rtlot2rplnboq7/Syntrix (TheBridgeAblaze) (3c75ed64-df6c-44f2-b2f5-2470bba08f26) (LAX-123ABCDFGHI) (934475968).savegame?dl=0
