Killing untargetable NPCs
The game may glitch in some live-with missions, where the objective NPC will become stuck behind a wall, and thus cannot be targeted. He may appear briefly, but you will not be able to maintain a lock on him. Walk towards the wall and enter the /kneel action to see through the wall. You can then click and target the NPC to complete your mission objective.
