Phenomenum's post in BUG Gift from the machine not givin after quest was marked as the answer
Just install the mod. Download a "General Reward Talents" and copy "GiftFromTheMachine" folder into your "override" folder. If you don't used mods before, then create it: ....Pillars of Eternity II Deadfire\PillarsOfEternityII_Data\override
No need to mess up with Unity Console - it may introduce stutter.
