I'm having the same issue, after fully upgrading the quiver and rations I'm unable to find any more fabric.

After giving the coin to start the arrow's challenge and starting the challenge by saying "I'm ready" the Norse warrior doesn't continue speaking after saying "our current champion the sear" afterwards the challenge doesn't start. Avior isn't able to move or shoot.

@guest-ixkn17ot I'm having te same problem as mentioned in point 2. When starting te bow challenge in "firing the arrow", Avior isn't able to fire. I've tried loading older saves, pledging to others regions,doing "bleeding the Leech" quest first,... Nothing works
