📋 About This Mod

Heather update to v2. 7

February 16, 2024

This update does not require a new save but you do need to replace your current v2.x version with the new one. Do not merge. Old scripts, etc. not removed can cause issues in gameplay so it's important to replace your old version completely with the new one.

What you should know:

v2. 7 is primarily a bug fix, however I did add one, new feature. Heather can now be dismissed to a settlement. She is also assignable in Sim Settlements 2. See Change Log for complete list of fixes.

Be sure to check out the OPTIONAL FILES found in the FILES tab if you need:

1 - Bodyslide Files for Heather's outfit.

2 - A patch that will override any lighting mod you use that makes Heather's bunker either too dark or too bright.

3 - You would like Heather to not use CBBE at all (default textures, outfits, etc are vanilla)

4 - You would like to remove all mention of Shaun or the player's spouse from Heather's dialogue.

5 - You play VR and need an esp with the header changed to . 95.

I will update the xbox version to v2. 7 after the FO4 updates are done.

If you are UPDATING from  V1.x to V2.x you should never update to the latest v2 version into a save that is currently using v1.x. The mod will be riddled with bugs if you attempt to do that. Please use CTRL F to search for "THINGS TO KNOW ABOUT HEATHER V2" if you want to know more about installing the latest v2 version if you are playing v1.x.

GENERAL INTRODUCTION

Heather is a caravan trader who grew up in the Commonwealth. She hates and distrusts synths, wishes she lived before the war when everything was nice, believes in aliens and has heard that pre-war donuts were delicious. Heather is a complex companion similar to the vanilla companions in concept with over 2200 lines of custom, voiced dialogue that is delivered throughout the Commonwealth, Far Harbor and Nuka-World . She comments during quests, in specific locations, in random chatter and in conversations with the player and other NPCs. Heather has a tragic past, like most everyone else in the Commonwealth, and when you meet her she still feels that loss acutely. By completing the quest Sweet Revenge you will help to heal her wounds letting her move on with her life. As time goes on her history will be revealed to you through conversations, general chatter, stories and terminal entries. When you first meet her she hates synths and thinks the BOS is awesome, but she'll support you no matter which of the four factions you
