BeamNG Mod Manager 🧡 v0.6.6: Reliable Imports, No More “Duplicate” Clutter & App close bug fixed

BMM v0.6.6
Released July 3, 2026

This is a big quality-of-life release, and it fixes one of the most annoying things people have run into. 🧹 If you’ve ever ended up with a pile of “- Dup” copies after a reinstall, this one’s for you.

🎯 The big fix: no more phantom duplicates 

Bringing in mods you already had no longer creates confusing “ - Dup” copies. When BMM finds mods already sitting in your Mod Storage folder — after a reinstall, a reset, or when you point BMM at an existing library — it now recognizes them and reconnects your active set instead of making duplicates. Importing from your game folder simply says “Reconnected N mods,” and nothing gets moved or copied. Clean and instant. 

🤝 Honest imports you’re in control of 

• Everything comes in, clearly labelled — drag-and-drop and “Add Mods” bring everything into your library — and if something really is a duplicate of a mod you already have, it’s imported too and flagged for you to review in the Duplicates tool. 

• BMM never deletes your files on its own — you stay in the driver’s seat; the import summary tells you exactly what happened instead of a misleading “unreadable.” 

• Even more honest Space Saved — deleting a duplicate that was only a hard link (sharing its data with another copy) no longer counts as reclaimed disk — because nothing was actually freed. 

🚪 A clean exit 

We squashed a sneaky bug where the app could keep running invisibly in the background (holding onto your data folder) and opening it again would silently start a second hidden copy. BMM is now single-instance again. lol 

• Launch it again and it brings your existing window to the front

• A window that fails to appear now shows itself within a few seconds

• A shutdown safety net guarantees the process actually exits when you close it

There’s also a tiny local troubleshooting log that records each launch and exit, just in case anything ever recurs — it stays on your machine and is never sent anywhere.

💡 Clearer onboarding 

Onboarding now explains up front that a mod showing in both your game folder and Mod Storage is the same single file in two places (a hard link) — not a wasteful second copy. Felt like one of those things that’s obvious once someone tells you, so I wanted the app to tell you. lol. 😅
