The brahmins walking together with the provisioners along the supply lines are now feral ghouls. They are not aggressive.
Existing brahmins seems to keep their original names since such information comes from the game saving, but the new ones should be named correctly. The same happens with the clothings if the character is changed or set back to the original brahmin. In this case, a clean save is needed to reset it properly.
How to have a clean save:
- Go to an interior location
- Hard save the game (“Save” and not “Quick Save”)
- Exit to Main Menu
- Delete this mod
- Load the hard save
- Make a new hard save (it’s the clean save)
- Exit to Main Menu
- Install this mod again
- Load the second hard save
