havnt seen this on the bugs forum so thought would post

ninja, mister sandman and deacons cloak and dagger perk do not multiply correctly

depending on which order you take them determines effects the multiplier

from wiki

• In http://fallout.wikia.com/wiki/Fallout_4, the bonus to the actual sneak attack damage multiplier on silenced weapons provided by this perk is known to behave erratically when interacting with http://fallout.wikia.com/wiki/Cloak_%26_Dagger and http://fallout.wikia.com/wiki/Mister_Sandman. There is 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 = 6.3x

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 (!)
