I noticed this as of 6/8/2026, and haven't quite seen a threat addressing it yet, just the new quest line that isn't out yet.
However, Quen, required to start the Hewsbane guild line, does not appear currently in any refuge on any character I've tried. This has caused the issue of not being able to progress or start the quest line on any character aside from the one who has completed it already.
Partners in Crime is the specific quest, and even checking the Windhelm docks resulted in her not being there.
