Duplicate Loot Drops When Killing Stacked Entities Using WildStacker

[yellrim]

Minecraft's Version

When killing only 1 entity from a stacked group using WildStacker, the server drops more than the maximum possible loot, as if 2 or more entities died, even though only a single entity was killed.

Plugin's Version

• Server Version: Paper 1.21.4
• WildStacker Version: WildStacker-2025.2
• Weapon Used: Netherite Sword
  • Looting III
  • Sharpness 100
• Entity Type: Cow
• Stack Size: 16 cows merged into one stack

Describe the bug

A stack of 16 cows was killed using a Netherite sword with Looting III and Sharpness 100.
When killing only one cow from the stack, the entity drops more than 6 items, which should be the absolute maximum possible for a single cow with Looting III.

This indicates that WildStacker may be applying loot calculations incorrectly, possibly treating the kill as if more than one entity died.

To Reproduce

1. Create or find a stack cows using WildStacker.
2. Feed wheat to cows and let them breed
3. Equip a Netherite sword with Looting 3 .
4. Attack the stacked entity once to kill only 1 cow.
5. Observe the number of dropped items.
6. The loot amount exceeds the expected maximum for a single cow.

Additional Information

Expected Behavior

• Only the loot of the single killed entity should drop.

• With Looting III, a cow should drop no more than 6 items total.

• Stacked entities should not produce excessive or duplicated loot.

• More than 6 items are dropped, which is only possible if multiple cows were counted as dead.

• Loot appears to be calculated as if two or more entities were killed simultaneously.
