About this mod Author’s original text

MonsterLabZ (Valheim 1.0 fix)

Explore Valheim with new monsters to fight. This is a community patch of MonsterLabZFix 3.0.12 so the plugin loads on Valheim 1.0.

Original mod:

Previous restore:

All credits go to the original author DefendYourBase. Creatures, locations, and assets belong to them. Do not treat this as a new content pack.

What 3.0.13 fixes

Valheim 1.0 added float GetHoverOffset() to the Hoverable interface. MonsterLabZ.ML_PlantGrow did not implement it, so the type failed to load:

The script 'MonsterLabZ.ML_PlantGrow' could not be instantiated!

VTable setup of type MonsterLabZ.ML_PlantGrow failed

That blocked prefab registration. This build adds GetHoverOffset() (returns 0).

The in-game plugin version string may still read 3.0.12. That is expected.

Install

Install on client and dedicated server. Remove any other MonsterLabZ / MonsterLabZFix DLL first so you only have one copy.

A handful of creatures spawn by default. Configure the rest with Spawn That or the official BepInEx Configuration Manager.

Notes

  • Missing prefab hash on an old world can continue after this fix if leftover objects were saved when the plugin was broken. A new world is the clean test.
  • This package is a compatibility patch. If the original author updates MonsterLabZ for 1.0, switch back to that.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.

Dependencies

Install these first, or the mod will not work:
