Fix Version/s: Minecraft 1.13-pre6
Item stacks with a count > 1 generated by loot tables are spread into multiple smaller item stacks even if there is not enough place in the container resulting in a loss of items and the following warning message:
- Create a loot table which generates 27 item stacks, with some of them having a count > 1
- Save it for example in a data pack under \data\loot_tables\custom\test_loot_table.json
- Load the world and place a chest with the loot table
- Open the chest
→ You will notice that it contains less than 24 swords, but the torch item stacks are split into more than 3. Additionally a warning should appear in the log: "[Server thread/WARN]: Tried to over-fill a container"
Based on 1.11.2 decompiled using MCP 9.35 rc1
The problem is that the method net.minecraft.world.storage.loot.LootTable.shuffleItems(List<ItemStack>, int, Random) only calculates the amount of free slots once and not in every iteration and additionally the amount of stacks which should be split is not subtracted.
