The drink of the Picts quest on the Isle of Skye is bugged - the NPC says his bit about losing a list, I go in the house and find the list. Fine. I say I have the list, he says go collect stuff...so I do. But on returning to him, I just get the same dialogue "could you collect these for me"
I have tried only collecting one of each item. Tried collecting 10 fireflies. I have tried meditating during the quest. Tried arriving at night so no meditation. Tried loading saves from hours previous and trying again from scratch. Tried fast travelling. Tried setting his house on fire. Tried running him over with a horse. Tried approaching from each point on the compass. Tried rebooting. Tried pulling plugs midgame.
Could do with a hint or some help please!
