Unofficial Fallout 4 Patch

To whom it may concern,

I have reported this bug(s) on the fallout 4 forum here, on Nexus mods, and on steam. After reading the FAQ here, i found for posting this is the correct place to post it, so i am posting all relevant information here.

First off, this has to do with the NUKA WORLD DLC.

Second, this is a bug affecting the base game. I have no mods i use. I am not even using the UF4P atm.

Third, there are two parts of this bug that are on the same quest. Because the quest has two different bugs associated with it, I will post them together on this topic.

Here is a description of the bug(s) associated with this quest i have found. Note that i have confirmed this is actually a bug myself, does not affect everyone who plays the game, is somewhat common, and breaks the quest basically. I am coping and pasting a post i put on nexus mods site because it is easier to do than to look for each link about the issue again:

The following are some links confirming this quest has this bug and is not only effecting myself personally:

Apparently someone also posted even on Bethesda.net, with a weird workaround:

Same but also on consoles too:

It could be where your standing, but i don't think it is..i think it is a bug, and a common one at that. It appears that it did not effect you i guess your lucky. It seems likely it is a bug since it seems to effecting several people playing the game:

Considering it also made more problems even after i was forced to use the switch ending. First, Sierra was still unresponsive, and when i went outside and back in, she gave both sad and happy answers when talking to her, but her location was still at end of stairs. In other words, she was talking to me with lines like i did not unplug the head guy, and also at same time giving me sad lines. Second, my UI was gone. I had to go out of my power armour to actually fix it. Third, Piper (the companion i was using!) went invisible. Even though she was talking to me and walking around with me, according to the overseer tracker thing, she became invisible. Leaving and re-entering the map did not work. It also made it so i cannot give Sierra the Cola Recipe, so it broke the quest, making it so you cannot progress further into the quest, or to be more precise, actual being able to finish it..

NOTE: If im "forced" to use console commands to fix it, it is breaking my immersion in the game and means it is a bug as it was not designed to do that.
