While this patch doesn't strictly require FROST, it's definitely intended for FROST.

Who is Opal? In vanilla FO4 she is an overlooked, pointless vendor in the Financial District. In FROST she is probably the most important vendor in the game but she has several shortcomings.
Problem: Her inventory doesn't reset properly. If you sell her an item, it clogs her inventory forever.
Fix: Items you sell her now disappear from her inventory when her inventory resets.
Problem: There is nowhere to buy 762 or 45-70 ammo in vanilla FROST. Once you run out of 762 ammo, it's gone forever.
Fix: The handmade rifle, radium rifle, lever action rifle, and their associated ammo types have been added to Opal's inventory.
Problem: Opal is mortal. She lives right next to a random encounter spawn point that frequently spews out ghouls. Human NPCs in FROST don't know to aim for the head so they almost always die to ghouls. Even though it's unlikely for a ghoul to climb all of the stairs to eat her, it's annoying having to babysit her every time you leave Valenti Station.
Fix: Opal is now marked as an essential NPC. She and Garvey will live on forever.
