BeastheimLegacyCompat
Repairs known Valheim 1.0 API breaks in supported mods, applied in memory at load time. Original mod files are never modified or redistributed; unsupported versions are left untouched.Beastheim Legacy Compat
A safety-net patch for mods that haven't yet been updated for Valheim 1.0.
Some older mods call game functions whose signatures changed in the Valheim 1.0 update. Rather than crashing, this patch repairs those specific calls at launch — in your own already-installed copy of the affected mod, in memory, every time you start the game.
What it does
At startup, this checks every mod you have installed against a list of known, individually verified Valheim 1.0 compatibility breaks. If (and only if) an installed mod's exact, reviewed version matches a known break, the fix is applied at load time, in memory, for that session — your original mod file on disk is never overwritten, never permanently modified, and is not redistributed by this patch in any form. If a mod isn't affected, or is a version this patch hasn't specifically reviewed, it is left completely untouched — unreviewed versions are never guessed at.
This patch does not add content, change gameplay, or require configuration. You should simply have it installed alongside any of the mods below.
Currently supported
| Mod | What's repaired |
|---|---|
| Dvergr Pieces | A renamed internal field, and a compile-time constant that crashes on load |
| Valheim Cuisine | The same constant-crash issue, plus a null-reference guard for the Freydís piece that otherwise breaks saved-world reloads |
| MonsterLabZ | A changed effect-creation call |
| OdinBanners | The same compile-time constant issue |
| OdinsSteelworks | The same compile-time constant issue |
| SmarterContainers | A changed inventory-notification call and effect-creation call |
This list only grows when a new break is found, reviewed, and verified — never guessed. If you don't have any of the mods above installed, this patch does nothing and costs nothing.
