The Fallout 4 Unofficial Patch will include item, quest, object, NPC, gameplay and text fixes. It's been said that it is a safe mod to use since it will not tingle with the game stock objects, etc. We would like to include a list, but it would be very, very long. I am not lying, check it out: (Here be the improvements!)
Your game has to have Patch 1.5.146 for installing the patch and the developers say that it is compatible with "as many other mods possible." You can download it here. Good bugless hunting & go bury those radroaches!
