Im having the same problem and its definitely deep into the night. Theres a moon showing on my timeline and i killed Barghests. But when I click a eternal fire thing it opens my inventory and right clicking the candles does nothing, double clicking them he always says "I promised the reverend id light these at night."I dont have a gift slot, ive seen that when talking to certain NPCs, but at the chapels I only have a slot that shows a potion being put into a chest. Dragging them into that box he just repeats the same line as above.What am i doing wrong? I checked the nice big manual that came with the game but as usual, a manual can be 5000 pages and never have your answer lol.
