🔧 トラブルシューティング & よくある質問

📌 リポジトリソース免責事項：本 Wiki ドキュメントはリポジトリ内の現在のソースコード状態を反映しており、CurseForge および Modrinth での公開ビルドに先駆けた最新の未リリースコミットや開発中の機能を含む場合があります。

1. Brewing Stand Interactions & Slot Splitting

Vanilla Minecraft's BrewingStandBlockEntity hardcodes slot capacity to 1 for the three potion input slots (SLOT_BOTTLE_1, SLOT_BOTTLE_2, SLOT_BOTTLE_3).

Potion Stacker Addon respects brewing stand slot constraints: when shift-clicking, exactly 1 potion is smoothly deposited into each empty brewing stand slot, while the remaining 15 potions remain safely stacked in your inventory.

2. Hopper Transfer Mechanics

Hoppers transfer stacked potions according to container slot limits:

Hopper -> Chest / Barrel / Shulker Box: Hoppers push full stacks into containers up to potionLimit (default: 16) at vanilla hopper transfer speed (1 item every 8 game ticks).
Hopper -> Brewing Stand: A hopper pointed into a brewing stand can only deposit 1 bottle per brewing slot.
Hopper -> Hopper: Hoppers pass stacked potions seamlessly between each other without splitting or ejecting items.

3. Ghost Items & Desynchronization Prevention

In vanilla Minecraft, changing stack sizes dynamically without refreshing container state can cause "ghost items". Potion Stacker Addon completely eliminates this issue:

Network Sync Packet: Whenever potion_limit or stew_limit changes, the server broadcasts a PotionLimitSyncPayload to all connected clients.
Dynamic Menu Refresh: The server immediately invokes broadcastFullState() on both the player's active containerMenu and inventoryMenu.

java

if (player.containerMenu != null) {
    player.containerMenu.broadcastFullState();
}
if (player.inventoryMenu != null && player.containerMenu != player.inventoryMenu) {
    player.inventoryMenu.broadcastFullState();
}

4. Multi-Addon Priority & Coexistence with Stew Stacker Addon

Potion Stacker Addon includes an intelligent fallback delegation check in PotionStackerManager.java:

java

if (isStewOrSoup(item)) {
    if (FabricLoader.getInstance().isModLoaded("stew-stacker-addon")) {
        return -1;
    }
    return stewLimit;
}

If stew-stacker-addon is NOT installed: Potion Stacker Addon provides convenient fallback stacking for Mushroom Stew, Rabbit Stew, Beetroot Soup, and Suspicious Stew up to stewLimit (default: 16).
If stew-stacker-addon is INSTALLED: Potion Stacker Addon detects the mod and returns -1, completely yielding all soup and stew stacking calculations to Stew Stacker Addon.

5. Maximum Stack Limits & Integer Safety

Under the Player Agency & Anti-Nanny Invariant, players and server owners are given total freedom to set stack limits up to Integer.MAX_VALUE (2,147,483,647).

A standard Large Chest has 54 inventory slots.
If every slot contains 39,768,215 items: $$\text{Total Items} = 54 \times 39{,}768{,}215 = 2{,}147{,}483{,}610 \le 2{,}147{,}483{,}647$$
Setting values greater than 39,768,215 can cause vanilla integer overflow in 32-bit container math. Values below 39,768,215 are 100% safe across all containers.

6. ASCII Diagnostic Decision Tree
