you can pick up the lemons at Location 1,-16 in the city of Astrub from the shop in the middle that LOOKS like a grocery store
The buthchers shop you CANT miss, its got a huge skeleton of something on it and it isnt very hard to find. Then you go back and talk to The girl that gave you the quest again and you have to fight here ! dont worry, she kicks the tar out of you . And sends you on ANOTHER quest. Who does she think she is really ? And then you go down to 4,-13 and all the sudden it says your done? whoa !
