🎯 Tips & Tricks
If you're using a mod manager like Vortex or MO2, just download and install—it'll handle the file placement.
Make sure your game version is 1.10.163 or older; this mod won't do anything if you've already updated.
If you're a mod author, this lets you create BA2 archives that work for both old and new versions—test with this installed.
