Same here, for Rush we redid it 2 times and nobody got credit for it.
Bounty worked.
Trek was awful, 3/4 of the people doing it never got credit cause you have to touch the points, which is dumb.
Puzzle was the same, 3/4 of the people who did it got nothing for it, the others magically got credit.
Would be nice if guild missions were built on getting more people to do them, so that more guild members intermingled, and worked together, instead of the buggy, competitive mess they are right now.
