So me (Elite Process), VRENDEN13, and Jenandtonic1224; just beat Pillar of Autumn LASO (Legendary all skulls on) and at the very end of the game where the cut scene is supposed to play we got a message saying that there was a game error in Co-Op campaign. We still have the video where we completed the game and it will be uploaded to my file share where you can see that we beat the mission; and we did not receive our credits or our weekly challenge completion for beating the mission LASO.
If anyone knows where I should report this, please let me know.
Thanks, in advance.
