AzuModsValheim1Compat

AzuModsValheim1Compat is a lightweight BepInEx Preloader compatibility patch for Valheim 1.0.7 (Unity 6 update). It resolves the game-crashing MissingFieldException: Field not found: .ZRoutedRpc.Everybody in mods created by Azumatt (including AzuCraftyBoxes, AzuAutoStore, and others).

[!IMPORTANT] Temporary Compatibility Patch: This is an unofficial community fix intended to keep your favorite mods functional until the original author, Azumatt, releases official updates. Once official updates are released on Thunderstore, you can simply uninstall this patch.

The Problem Explained

With the release of Valheim 1.0.7 (Unity 6 engine update):

• The game's internal ZRoutedRpc.Everybody field was changed from a public static readonly long field to a public const long (compile-time literal).
• Older versions of Azumatt's ServerSync library embedded inside his mods attempt to read this via the IL instruction ldsfld ZRoutedRpc::Everybody.
• Under .NET / Mono CLR runtime, calling ldsfld on a compile-time literal throws MissingFieldException: Using static instructions with literal field inside the static constructor (.cctor()), completely preventing the mods from loading.

What This Patch Does

This patch runs in the BepInEx Preloader phase before the game engine starts plugins:

1. In-Memory ZRoutedRpc.Everybody Restoration: Converts ZRoutedRpc.Everybody from a compile-time const back into an active runtime static field in memory. No mod DLLs need to be modified on disk! ServerSync and all Azumatt mods run cleanly without metadata corruption.
2. API Compatibility Bridges: Injects backwards-compatibility bridge methods into assembly_valheim.dll for breaking changes introduced in Valheim 1.0.7:
   • PlayerProfile.m_itemCraftStats: Injects missing m_itemCraftStats dictionary and auto-initializes it in constructor (fixes Blacksmithing character select & save/load crash).
   • Inventory.Load: Renames redundant 2-parameter overload to eliminate AmbiguousMatchException in Harmony patches (fixes AzuAutoStore InventorySelectSameItemAfterLoad).
   • InventoryGrid.OnRightClick: Restores OnRightClick(UIInputHandler) method and redirects UpdateGui (fixes AzuAutoStore Favoriting and button handling).
   • Inventory.AddItem: Restores 8-parameter overload (fixes Smoothbrain's ItemDataManager shared library in Cooking, Blacksmithing, ExtraSlots, and EpicLoot).
   • ItemDrop.ItemData.GetTooltip: Restores 5-parameter static overload (fixes Blacksmithing & Cooking crashes).
   • Character.Message: Restores 4-parameter overload.
   • SEMan.AddStatusEffect: Restores 4-parameter overloads (both StatusEffect and int hash).
   • Inventory.IsTeleportable: Restores 0-parameter overload.
   • Inventory.AddItem: Restores 4-parameter overload.
   • EffectList.Create: Restores 5-parameter overload.
   • Terminal.ConsoleCommand: Restores 12-parameter constructor.
   • InventoryGrid.Element: Restores nested type definition referencing new InventoryElement.
3. AzuCraftyBoxes EpicLoot Compatibility: Automatically updates EpicLootEnchantingUI patches in AzuCraftyBoxes.dll to reference the merged EpicLoot assembly, resolving TypeLoadException: Could not load type 'EpicLoot_UnityLib.InventoryManagement' from assembly 'EpicLoot-UnityLib'.
4. VisEquipment.AttachArmor Call-Site Upgrading: Automatically upgrades legacy 2-parameter AttachArmor calls in plugins (such as MagicPlugin) to the 1.0.7 3-parameter signature without colliding with EpicLoot Harmony patches.
5. Blacksmithing Transpiler Compatibility: Automatically bypasses foreign hook scanning in Blacksmithing.ApplyTranspilerToAll, eliminating InvalidOperationException: Sequence contains no matching element in Unity 6 when playing with AzuCraftyBoxes.
6. In-Memory Inventory.AddItem Transpiler Compatibility: Provides the expected ZLog.Log placeholder inside the 4-parameter Inventory.AddItem bridge so outdated transpilers (like AzuAutoStore / MUC RemoveLogging) succeed in memory without throwing ArgumentOutOfRangeException. This completely unblocks ItemDataManager (Cooking, Blacksmithing, ExtraSlots) and ensures character creation and character saving (Inventory.Save / OnNewCharacterDone) work seamlessly without any exceptions.
7. Allows your modpack to load smoothly and cleanly!

Українська (Опис українською)

AzuModsValheim1Compat — це прелоадер-патч сумісності BepInEx для Valheim 1.0.7 (Unity 6). Він усуває критичну помилку: MissingFieldException: Field not found: .ZRoutedRpc.Everybody Due to: Using static instructions with literal field у модах від Azumatt (AzuCraftyBoxes, AzuAutoStore, AzuExtendedPlayerInventory та інших).

Що робить патч:

• Під час запуску гри (Preloader) перевіряє плагіни в папці BepInEx/plugins.
• Знаходить збірки модів Azumatt та замінює застарілу IL-інструкцію звернення до ZRoutedRpc.Everybody на коректну константу 0L.
• Створює резервну копію оригіналу (.orig.bak).
• Дозволяє користуватися модами без вильотів та зависань!

[!NOTE] Це тимчасове рішення для спільноти. Як тільки Azumatt випустить офіційне оновлення своїх модів на Thunderstore, цей патч можна буде просто видалити.
