🎯 Tips & Tricks
Make sure you have all DLCs installed—Heather's content spans Far Harbor and Nuka-World, so missing DLCs will break her quests.
Use a mod manager like Vortex or Mod Organizer 2 to avoid manual file conflicts, and place Heather's mod after other companion overhauls.
If you're on PC, check the mod page for any compatibility patches with popular mods like Sim Settlements or Armorsmith Extended.
