@ubi-peach I fixed it. I went back to an old save last month and ran though the Skal mission series once again and this time I killed Sigfried in the first attempt. That allowed the mission to end properly
I'm stuck in Francia DLC without any ability to FT or change regions. Save feature seems to be broken as well. Nothing I try has fixed the problem. I cant even travel to the next quest marker over-land because I get Desynchronized!
