This mod adds a completely new settlement to your game: Briar Valley. Briar Valley is fully functional, and will act like any other settlement. It is located on the west side of the map, directly south of the Federal Ration Stockpile. The green building perimeter in workshop mode is not exact, but will give you a good estimate of the allowed building area. Also, settlers sent from other settlements may take a few days to arrive, but will show up eventually. However, through my own personal experience, I would recommend using only a recruitment beacon - it seems to be more reliable as sent settlers don’t always arrive (some do).
Although this settlement has generally worked well for me, I would highly recommend backing up your save files before using it. I would also be careful when sending companions to this settlement, even though I have tested it many times and they will in fact show up. I would just hate for a companion to get “lost” because of this mod ;)
KNOWN BUGS
~When you first download the mod, the green build area border will appear outside of workshop mode. This is an easy fix - simply enter and then exit the workshop and it should go away.
~Settlers don’t always go to bed, and will often remain where they are assigned instead. I haven’t found an actual solution to this yet, but would recommend manually assigning settlers to beds as it sometimes helps.
Please let me know if you encounter any issues, and thank you for downloading!
