Valheim 1.0 permanently marks any character that has ever run devcommands as ineligible for Steam achievements — including retroactively, for saves that used the console during Early Access. This tool reads your character file, tells you whether it’s flagged, and hands back a fixed copy that changes only that one flag (plus the file’s checksum). Skills, inventory, map, and world list are left exactly as they were.
Nothing is uploaded — the file never leaves your computer- Launch Valheim and select the character you want to clean — don’t enter a world.
- Click Manage saves, then Move to local. (Skip if it’s already a local character.)
- Close Valheim entirely.
- Open the folder it was moved to — paste this into the File Explorer address bar (
AppDatais hidden, so it won’t show by browsing):
%USERPROFILE%\AppData\LocalLow\IronGate\Valheim\characters_local - Confirm <your character>.fch is there. You want the
.fchfile — not the.fch.oldnext to it (that’s Valheim’s own backup).
- Drop that .fch onto the box above (or click to pick it). Everything happens in your browser — the file is never uploaded.
- The tool shows the character and whether the cheat flag is set:
• Flag present → click Download cleaned <name>.fch.
• Flag absent → the character is already clean; there’s nothing to download. - The cleaned file is your original with one byte changed (the flag) and the file’s checksum recomputed. Skills, inventory, map, and world list are untouched.
- If the tool also lists cheated items, those are console-spawned items still in your inventory. They block achievements on their own — drop them in-game once the cleaned character loads (step 3).
- Copy the downloaded .fch into characters_local, overwriting the existing file. Keep the same name. (Back up the original somewhere first if you want a safety net.)
- Optionally delete the matching
.fch.old— not required, but harmless. - Launch Valheim. Don’t move the character back to the cloud yet.
- Load the character, enter any world, and open the Achievements tab — you should no longer see the “permanently disabled” message.
- If it checks out, return to the menu and Move to cloud to re-enable Steam Cloud sync. The fix survives the round trip (and joining multiplayer servers).
What counts as cheated. Only three things block achievements: the character cheat flag (what this clears), any item in your inventory that was spawned via console, and playing on a world with modifiers the settings screen can’t produce. Command history shown by the tool is cosmetic — it doesn’t affect eligibility.
Older saves. The tool only understands Valheim 1.0 character files. If you get a version error, load the character in Valheim 1.0 once (which upgrades it) and try again.
Checksum. The file ends with a SHA-512 of its contents; the tool recomputes it so the game loads the edited file without complaint.
