I've reset my perks, sold all the mod besides the quest item uncommon Ping that is impossible to remove (several duplicates up to epic level, so did work for some time), even changed my cyberdeck. Nothing works.That lines up with some comments I read on youtube regarding players which claimed, that they resetted skillpoints and were able to loot quickhacks again from access points afterwards. Maybe there is just a certain order in which these skills have to be learned to make it work again.
Beyond the (for me) game breaking bug, the design is poor. There should be a much more noticeable audiovisual notification when you score. Instead, these sneak up in your inventory like a ninja. Unless you're bugged like me and countless others.
