What the game is supposed to be doing is sending players to groups of similar leveled players when starting from the mission select screen. The bug is apparently not following the games directions and is sending players to the very last mission in the game.
Twitch streamer “Brandon Larned” was able to share his experience with this weird bug where it also shows a level 3 player joining his battle. Quickly after the level 3 player left the match, another low level player joined and was not able to leave the battle.
Thanks to some reddit users, we also know that there are issues with the level indicator on some players. The only thing that is being recommended as of right now is to completely skip quickplay until this bug is patched. Ben Irving, Anthem’s lead producer has confirmed that this is in fact a bug.
