Harvesting from sweet berry bushes can drop more sweet berries than before

The bug

In 25w32a, a dedicated loot table for harvesting sweet berry bushes is introduced. However, the drop count for sweet berries is different than previous versions:

• In 1.21.8

  • Third growth stage yields 1-2

  • Final growth stage yields 2-3

• In 25w32a

  • Third growth stage yields 1-3

  • Final growth stage yields 2-4

This is not mentioned in the 25w32a changelog, so I believe it is a bug.

To Reproduce

1. Run the command

/fill ~ ~ ~ ~9 ~ ~9 minecraft:sweet_berry_bush[age=3]

1. Right-click on the sweet berry bushes.

2. Take note how many sweet berries you can obtain in a single harvest.

Observed Result

You sometimes obtain 4 sweet berries in a single harvest.

Expected Result

You only obtain no more than 3 sweet berries in a single harvest.

Analysis

The issue lies in the corresbonding loot table, which is located in data/minecraft/loot_table/harvest/sweet_berry_bush.json:

{
  "type": "minecraft:block_interact",
  "pools": [
    {
      "bonus_rolls": 0.0,
      "entries": [
        {
          "type": "minecraft:item",
          "conditions": [
            {
              "block": "minecraft:sweet_berry_bush",
              "condition": "minecraft:block_state_property",
              "properties": {
                "age": "3"
              }
            }
          ],
          "functions": [
            {
              "add": false,
              "count": 1.0,
              "function": "minecraft:set_count"
            }
          ],
          "name": "minecraft:sweet_berries"
        }
      ],
      "rolls": 1.0
    },
    {
      "bonus_rolls": 0.0,
      "entries": [
        {
          "type": "minecraft:item",
          "functions": [
            {
              "add": false,
              "count": {
                "type": "minecraft:uniform",
                "max": 3.0,
                "min": 1.0
              },
              "function": "minecraft:set_count"
            }
          ],
          "name": "minecraft:sweet_berries"
        }
      ],
      "rolls": 1.0
    }
  ],
  "random_sequence": "minecraft:harvest/sweet_berry_bush"
}

We can conclude that the loot table always drops 1-3 sweet berries, and additionally drop one more if its age is 3, which demonstrates the bug behavior.

To fix the issue, simply adjust the maximum count at line 40:

"max": 3.0,

to:

"max": 2.0,
