Don't know if I'm missing something, but bribe destiny can be turned on in tweaks just like in keep without having the perk.
Rapti I believe said that the option wasn't meant to be included in the menu since you had the option to buy it and I think he said it will not appear in the next update.
Yeah, I messed up copying the settings screen over from Keep. It'll be fixed when I update. I'm just giving it a day or so for bug reports to filter in.
