[4.1] Bug: Actors and Containers - _onDropStackConsumables only stacks Potions of Healing (specifically, Compendium.dnd5e.items.Item.ytlsBjYsZ7OBSEBs)

[kgar]

On actors and containers, when you drop a consumable item onto the sheet, it no longer stacks, unless it is the item with source UUID "Compendium.dnd5e.items.Item.ytlsBjYsZ7OBSEBs", i.e. a Potion of Healing.

Line 44 in a1d6aa9

const similarItem = this.actor.sourcedItems.get("Compendium.dnd5e.items.Item.ytlsBjYsZ7OBSEBs", { legacy: false })

The code in question:

  _onDropStackConsumables(itemData, { container=null }={}) {
    const droppedSourceId = itemData._stats?.compendiumSource ?? itemData.flags.core?.sourceId;
    if ( itemData.type !== "consumable" || !droppedSourceId ) return null;
                                                                              // 👇 That's a potion of healing from the SRD
    const similarItem = this.actor.sourcedItems.get("Compendium.dnd5e.items.Item.ytlsBjYsZ7OBSEBs", { legacy: false })
      ?.filter(i => (i.system.container === container) && (i.name === itemData.name))?.first();
    if ( !similarItem ) return null;
    return similarItem.update({
      "system.quantity": similarItem.system.quantity + Math.max(itemData.system.quantity, 1)
    });
  }

4.1.1 will remove system.quantity entirely and introduce the potionOfHealing item type, the only type able to stack.
