Save state
Any time you want to save your current character state, to protect from crashes, open your skill menu and click accept. This will save your character's experience total, and will load from this point in case of a crash.

Dealing with glitched mission objectives
During some live-with missions, the objective NPC will be stuck behind a wall, and can't be targeted. You might see him briefly, but can't maintain a lock because he's behind a wall. To complete your objective, walk towards the wall and use the /kneel emote, to see through the wall. You can then click on him, and complete the mission.
