Changelog

1.2.2

• Preserve the cheated-item provenance flag when a successful hopper pickup merges into an existing stack.
• Keep the destination's existing count and flag unchanged when pickup fails and insertion is rolled back.
• Clarified core fuel rules, Black Core consumption, configuration, multiplayer requirements and the remaining network transaction limit.
• Updated package dependencies to the checked Valheim 1.0.16 setup.

1.2.1

• Fix the startup IL Compile Error / Unexpected null involving SurtlingFuel's obsolete Character.Message call.
• Replace legacy manual-fueling and core-RPC execution with current-API handlers; stop patching the broken dependency methods.
• Keep the smelter/blast-furnace allowlist and receiving-owner checks, including explicit rejection of core fuel on other machine types.
• Route ItemHopper honey and dropped-item pickups around their obsolete inventory methods, preserving item metadata and checking insertion success.
• Preserve coal preference, configured core values, speed behavior, BlackCore support, and existing config settings.
• Require matching patch versions on server and clients so broken 1.2.0 clients cannot take over machine processing.
• Add a Mono regression fixture that reproduces the old error and checks all 16 new Harmony target wrappers plus fuel edge cases.

1.2.0

• Rebuilt against Valheim 1.0.12 and matching BepInEx core assemblies.
• Adapted SurtlingFuel 1.4.0 message and fuel-effect calls to the current game API.
• Updated ItemHopper 2.0.0 filter ghosts to InventoryElement and its dropped-item/beehive inventory insertion calls to the current signature.
• Replaced hopper coal and core fuel access with current API calls and cached network-view reflection.
• Fixed hopper ore delivery for the new RPC_AddOre payload, preserving each source item's real cheated/provenance flag.
• Added receiving-owner coal/core separation checks and rejected nonpositive core-fuel requests.
• Preserved the fixed smelter/blastfurnace allowlist, Eitr Refinery rejection, BlackCore option, and synchronized additional-fuel config.
• Requires BepInExPack Valheim 5.4.2350 and Jotunn 2.30.0. Live game verification remains required.

1.1.0

• Restricted every SurtlingFuel core-fuel path to the exact vanilla prefab names smelter and blastfurnace.
• Prevented manual fueling, hover-text changes, speed changes, core-state updates, and RPC fuel addition on all other Smelter-based machines, including the Eitr Refinery.
• Added an owner-side guard to SurtlingFuel's generated core-fuel RPC handler so another mod cannot bypass the machine restriction by invoking the RPC directly.
• Restricted ItemHopper core acceptance and transfer to the same two-machine allowlist.
• Clear stale SurtlingFuel core-state markers from disallowed machines while preserving their existing generic fuel amount.

1.0.1

• Fixed FieldAccessException: Smelter.m_nview is inaccessible in the live game.
• Replaced direct access generated against the publicized developer assembly with one cached reflection lookup, matching SurtlingFuel's own runtime-safe approach.
• The 1.0.0 exception occurred during ItemHopper's eligibility check, before its removal/transfer method, so it blocked transfers but did not delete hopper items.

1.0.0

• Added correct ItemHopper transfer support for Surtling Cores through SurtlingFuel's core-fuel RPC.
• Added Black Cores to a server-synced additional-fuel list by default.
• Added support for more prefab names through one server-synced config entry.
• Preserved SurtlingFuel's coal/core no-mixing rule for automated hopper transfers.
• Limited alternative fuels to coal-powered Smelter machines.
• Added fail-closed method resolution so an incompatible SurtlingFuel update does not consume hopper items through the wrong RPC.
