Being developed by community members, the Unofficial Fallout 4 Patch sets a goal to eventually fix every Fallout 4 bug that hasn't been touched by the developers. The patch requires you to have at least the 1.5.146 version of the game. The patch includes following features:
- Hundreds of gameplay, quest, NPC, object, item, text and placement bugs fixed.
- Created by the authors of the Unofficial Oblivion and Skyrim Patch series.
- No unsafe changes (such as deletions of stock objects).
- Designed to be compatible with as many other mods as possible.
