Context of "Cook a shrimp on a range in Lumbridge" R9BM

This game has some really pointless achievements. You can tell there is an achievement because of the Runescore icon below the description. Did you notice your task completed an achievement that works towards the Beginner Lumbridge tasks? Area achievements are often completed during other tasks, and that's ok (rule 2.E3). You also had to find another range than the one in the Castle, as using that is locked behind a quest - if you check rule 2.R1, it states you have to use methods you already have access to - hence the other range.
