It seems that evil wizard was more nefarious than we thought. Not only did he throw all the items to the ground - he also moved some of the shelves! This meant items could not be organised in neat groups in the Leviathan Store.
Fear not - the shelves are now back in their neat, tidy places.
In case you wanted to do some extra organising, these are the group counts for the Leviathan store:
Books: x3
Toys: x2
Cheese: x5
Sushi: x10
Meat: x6
Bread: x4
Pastries: x3
Plants: x11
Potions: x7
Crockery: x5
Fruit & Veg: x3
Statues: x5
Clothes: x5
