Ever since i unlocked an achievement from the champions DLC i cannot unlock any further dlc achievement such as the I can see u achievement from the majestic DLC so if anyone has a solution please let me know and 343i please fix this!!!
The acievements are probably DLC linked. So you need to achieve these in the right DLC. (So you’ll need to do the “I can see u” achievement in one of the Majestic DLC maps)
This is a known glitch. Please see this thread. Please post there to show your support for fixing these achievements.
As MathGuy42 stated, this is something we have a team investigating.
