| Issue | Likely Cause | How to Fix It | | :--- | :--- | :--- | | | Normal first launch process. Outdated Lemon Loader. Corrupted patch. | Wait it out for up to 15 minutes. If it persists, ensure you are using the latest version of Lemon Loader that is compatible with your game version. Try patching again. | | "Restore App" Prompt Undoes Patch | You accidentally selected "Restore App" instead of "Open App". | You will likely need to reinstall Bonelab and go through the patching process again. Always select "Open App". | | Mods Not Loading in Game | Mods in wrong folder. Incompatible mod version. Missing dependencies (e.g., BoneLib). | Double-check the file path: Android/data/com.StressLevelZero.BONELAB/files/Mods . Ensure the mod is for Quest/Android, not PC. Check if a required library mod is missing. | | Game Crashes on Startup | Corrupted or conflicting mods. Version mismatch. | Remove all mods from the Mods folder. If the game works again, reinstall your mods one by one to find the culprit. | | Lemon Loader Fails to Patch | Missing OBB files. Corrupted Bonelab installation. | Ensure the OBB folder ( Android/obb/com.StressLevelZero.BONELAB ) is present and contains data. If missing or patching fails, you may need to reinstall Bonelab from the Quest Store. | | Long Load Times | Normal, especially after adding many code mods. | This is to be expected. The mod loader needs time to inject all the code at launch. Be patient. | Sideloading transforms BONELAB from a standard VR game
