===Overlay objects===

Stardew Valley 1.3 adds overlay objects (in <tt>location.overlayObjects</tt>), which are positioned on top of the normal object layer so you can have two objects on the same tile. (The game uses it for special find-item quests.)

Stardew Valley 1.3 adds an <tt>overlayObjects</tt> field to <tt>GameLocation</tt> instances. These have two special properties:

* They're not synced to other players, so each player has their own overlay objects. (That's used for special quest items, so other players can't take your item.)

* They're positioned on top of the normal object layer. (If there was already an object where the item is placed, the previous object will be hidden until you pick up the overlay object instead of being deleted.)
