Collecting skulls so I can attempt Halo 5 LASO and I encounted the issue. As far as I know the only proof you get for clearing LASO in Halo 5 is a Mister Chief Carnage Report back drop. So if anyone has a solution I’d be grateful to hear it!
Yea as far as I know there is no reward or tracker for H5 LASO so screenshot a post game report is likely your only bet, make sure scoring is on as I am pretty sure that matters. Other than that I know that post gam reports don’t always load in game, and unfortunately game history for campaign is not posted online either. If the game glitches out and doesn’t give you the report, you may just have to beat the mission againl.
