Installing a progression-heavy mod deserves a more careful process than dropping files into an old game folder and hoping for the best. This guide uses a backup-first workflow that protects your existing worlds and makes problems easier to diagnose.
Before you download
Create a copy of the game instance you already trust, including its saves and configuration. Keep that backup outside the folder you plan to modify. A clean rollback point is more valuable than trying to reconstruct a working setup after several changes.
Use a separate test instance
Prepare an isolated instance for Better Than Wolves Mod. Avoid adding unrelated mods during the first test. The goal is to learn whether the downloaded build and intended game version work together before introducing any extra variables.
Match the build to the game version
Do not assume a tutorial written for another continuation, loader, or historical build is interchangeable with the archive you have. Use notes that match the specific build and avoid mixing setup instructions simply because they mention the same mod name.
First launch checklist
Launch the clean instance before moving an important world. Confirm that the game reaches the menu, can create a fresh world, and remains stable during a short test. If it fails, collect the error information while the setup is still minimal.
Move saves only after verification
If you plan to use an existing world, duplicate it and open only the copy. Keep the original untouched until you know the build handles the world correctly. Never use the only copy of a long-term world as a compatibility test.
Practical next step
Keep your current working setup backed up, change one variable at a time, and document the exact build you are testing. That approach makes both gameplay learning and technical troubleshooting more reliable.
