I completed the "Crazy, Crazy, crazy quest by sneaking through Black Mountain with the help of Stealthboys. In doing so I didn't encounnter any Nightkin's or Super Mutants including the Nightkin sniper with the obvious exception of Neal. I repaired Rhonda and met up with the Tabitha to finish the quest. Next time I returned the Nightkin sniper was gone and obviously with it, Anabelle.

So is there any way of tracking him down or is the weapon forever lost now? That would kinda svck considering I'm an explosive char. Also keep mind I never killed him.

Then I'm afraid you're SOL, since once he disappears he's gone for good. I always make sure to kill him before repairing Rhonda so that I can get Annabelle, since I'm a big fan of explosives in general and Missile Launchers in particular.

Yeah, it gone for good. But it's not that big of a loss. Except for a slight decrease in weight and a higher value, Annabelle is basically a regular Missile Launcher with the Guidance System mod attached. Just get a regular missile launcher and you won't really be missing anything.

You forgot it has twice the durability.

BTW, is it true that Anabelle isn't affected by the Demolition expert perk? According to the Vault wikia it isn't when the Missile launcher apparently is. Is this an oversight or is it true? That would mean a regular Missile launcher would pack a whole lot more punch with high levels of this perk.

Presumably it's possible to spawn Annabelle with the console if you can look up the i.d.

Neither are affected by the Demolition Expert Perk. Here are the list of explosives that aren't affected:

- Dynamite
- Long Fuse Dynamite
- Time Bomb
- C4
- Missile Launcher
- Annabelle
- Fat Man

Maybe this upcoming patch will resolve this.
