I have the Hacker Overlord perk and I see a lot of epic quickhacks that I can make but for some reason "Whistle" isn't on the list? I also have the School of Hard Hacks and Hacker's Manual but Whistle shows up in NONE of the tiers. Do we need crafting specs for each quickhack or is getting the quickhack crafting related perks enough to be able to craft them?
