Guild quest shows as repeat quest when total guild progress is 0, right after choosing the guild quest after the weekly reset.
Here you can clearly see that the guild progress for the Bossrush weekly is at 0/20 lvl1, so it is impossible that a quest completion could have occured.
But my individual quest shows as a repeat quest and doesn’t award Bloodstones.
