Bugs

 * The bonus to the actual sneak attack damage multiplier on silenced weapons provided by this perk is known to behave erratically when interacting with Ninja and Mister Sandman. There does seem to be a bug with the calculations with all three perks active, depending on the order in which they were granted, as follows:

Sandman 3, Cloak, Ninja 3 = 5.9x Sandman 3, Ninja 1, Cloak, Ninja 3 = 5.9x Sandman 3, Ninja 2, Cloak, Ninja 3 = 5.9x Sandman 3, Ninja 3, Cloak = 5.9x Ninja 3, Cloak, Sandman 3 = 6.3x Ninja 3, Sandman 3, Cloak = 6.3x Cloak, Sandman 3, Ninja 3 = 6.3x Cloak, Ninja 3, Sandman 3 = 5.4x (!)


 * Further testing is needed, but right now the only solution appears to be selecting/receiving these perks in the "correct" order.


 * Obtaining the Cloak and Dagger perk may contribute to a bug where the combination of the Sniper perk and armor with the Stabilization mod being worn on both arms no longer prevents all sway when aiming down a scope. See the Sniper page for a potential work around.
