Currently I cant finish this weekly (week 2) challenge called "Ley Line Secrets" as I did not get the first 3 trivial mysteries last week. Am I just screwed or will the first version come back so we can get them again? I am a little confused with all of this and some of the challenges/triumphs being bugged is not helping. Also why cant we select those missions in the meny like when we swap to legend or master in a nightfall?
