[quote]Over the past month ive been trying to get the conqueror's discipline challenge finished but the problem is that solar and strand will not complete ive done it mulitple times using base solar and base strand then ive tried using prismatic solar/strand that also did not work could you please fix this for my account. Thanks bungie[/quote] It has to be a strike GM and not a battleground GM for that triumph to count. The triumph was released before battlegrounds were added to strike playlists so they're not coded as actual strikes.
