I've been trying to complete all of the triumphs for all the lost sectors but some of them don't seem to ever come into rotation. For example, I've gone so far as to keep track of when the ones I need should be active. I was expecting today to be concealed void (Europa lost sector) since yesterday was perdition and the day before was Bunker E15. Are they not on a consistent rotation? Or can they be made so that all lost sectors can be selected on any given day since they don't give specific armor slot exotics anymore? Thank you
