Hello all, I have a bit of an issue. I have collected atleast what i thought i had collected all the items. I returned to the Librarian in fcity. She took my items and said i didnt have enough. so i went and got the the left over items I did not have which was the Level 7 cookbook. I go back to return to finish quest and she still says i dont have all the items. Does this mean i need to hunt all those items over again? That Memory book took hours just to find 1 this is soo not cool if thats the case. Any suggestions or fixes for this?
