Achievement Sync

Client-side Valheim mod that keeps Steam achievements working while using mods and console cheats, and syncs previously recorded progress into the achievement track so already completed goals can unlock.

Features

• Steam achievements work with mods, devcommands, cheated items, and cheated world modifiers
• Syncs previously recorded progress (builds, piece removes, crafts, kills, pickups, food, etc.) on character load
• Re-checks achievement unlocks after sync
• Clears the “obtained through cheats” mark from player inventory, loaded containers, and world drops
• Blocks Inventory.ItemCheated checks used by CraftFromContainers-style mods
• Manual resync hotkey: F7 (configurable)

What sync can and cannot restore

Can restore: cumulative stats Valheim already saved — builds, kills, crafts, pickups, food, piece names, etc.

Cannot reconstruct: one-off events that were never written to a persistent marker while achievements were blocked. If Valheim never stored that progress, the mod has nothing to sync.

Install

1. Install with r2modman / Thunderstore Mod Manager (BepInExPack_Valheim required)
2. Or place LiveriaDevs.AchievementSync.dll into BepInEx/plugins/
3. Load your character in-game
