Does this happen with an unmodded fresh install right from the beginning?

Ist dein Spiel von Steam? Dort ist ebenfalls eine Einstellung zur Sprache. Ich kann allerdings nicht genau sagen welchen Einfluss diese Einstellung hat. ----------------------------- Is your game from Steam? There is a setting for the language, too. Can't exactly say which influence this setting has. Oder Du löschst die drei Ini-Dateien, lässt das Spiel Neue erstellen und machst danach alle notwendigen Einträge erneut. ------------- Or you delete the three ini-files, let the game create new ones and make all necessary entries afterwards again.

Hast Du mal die Fallout4.ini kontrolliert? Dort findet sich ein Eintrag zur Sprache. Normalerweise ist diese unter ....Documents\My Games\Fallout4. Es sei denn Du verwendest einen Modmanager welcher diese Datei an einer anderen Stelle hat. Was würde passieren wenn Du ein neues Spiel startest? Möglicherweise ist dieses Durcheinander in deine Spielstände eingebacken und dehalb funktioniert es auch nach einer Neuinstallation nicht richtig.

I am also not aware about a mod that lets you lay pipes above walls, but normally I would say that most plumbing pipes lie within walls and not above. If you want a mod with working showers, bathtubs, toilets and sinks you could search for "CWSS Redux 4.1". Former versions had the little flaw that characters are grinning after using a bathroom object and I believe the flaw still exists. But you want to make your settlers happy, right? In case you want to reset the facial expression you could use this mod: https://www.nexusmods.com/fallout4/mods/22051?tab=files

It's hard to dertermine what is a core mod, because every player has a different focus. When it comes to settlement building there would be the choice between realismn or, if you are not interested in nailing post war junk together, mods that bring pristine objects. So I, personally, would say that there are only a handful real core mods. Here on Nexus you have categories to go through. Always being aware about next-gen or pre next-gen. In addition there are graphics post processing tools like ENB and Reshade (I recommend to not use a newer one than 6.2....) which I think of as essential. Everything is a matter of taste, but some of the most important "core" mods for me are (pre next-gen): CBBE + Bodyslide and Outfit Studio (I know that there are other body replacers, but I will stay with CBBE) Photo Mode Screen Archer Menu Scrap Everything Place Everywhere Transfer Settlements and/ or Clipboard Resurrection Looksmenu Looksmenu Composing Compendium Better Console HUD Plus Plus Faster Workshop No mods, but important in my eyes: FO4Edit or XEdit The Creation Kit

Only as a last attempt: "help sarah 4" gives back NPC_D4000f99 SARAH for you, right? So the game still finds her, but her prid is "D40035C1" and not "D400035C1". Is this only a typo you made here or did you enter the prid with one 0 too much in game console, too?

There is a Mirelurk related quest on Spectacle Island. I don't know whether replacing the Mirelurks could break it.

In case information is shown you could try to use "showinventory" or "openactorcontainer" in console or use the Screen Archer Menu. And unequip every clothing. What happens if you try to teleport you to her? Or did you perhaps switch off her ai? You could try to open the console and type "prid 4d0035c1" + enter and next "tai" + enter. Either her ai was enabled is now switched off. In this case you need to repeat the command to reenable. Or it was switched off and is now enabled again. With switched off ai you can't move the character with "moveto" commands. I know that this normally no good idea, but if nothing helps sometimes you have no choice, but to uninstall/ disable the mod in question. With making a save before. Addition: "I then gave up and asked another companion to join me, when i did that, I was asked where I wanted to send Sarah? That meant she was near and invisible..." This doesn't necessarily mean she is near you. Only that she is your actual companion. You could try to use the option to send her to a settlement. If she really moves over there you at least know where she is. Her ai has to be enabled for this.

This is what I get when I click on Sarah with the mod Better Console. As you can see her ID is "E80035C1" and her baseID is "E8000F99". You need the ID. NPC_000d4cb5 SARAH of your post is from the base game and has nothing to do with "your" Sarah. So according to your post (with this result NPC_D4000f99 SARAH = baseID) her ID for you would still be "D40035C1". What happens if you simply type in Console "prid D40035C1" + enter? Does this bring up information on her?

Maybe I expressed myself a bit awkwardly. I meant K-L-E-O's role as a weapon trader breaks outside Goodneighbor and as a result her dialogue options change. So I thought that whatever triggers K-L-E-O's and Magnolia's behavior is found in and maybe limited to Goodneighbor and the Third Rail and that hereami might not find what makes Magnolia sing in her properties. As I said I am no expert in this.

Afaik moving K-L-E-O to a different location breaks "her" dialogues. Im no expert in this, but perhaps there is a script running that is not part of the actor, but of a location/ cell and only runs there.

I assume that you buildt in Sanctuary again what is needed for the mod and when it works at Red Rocket I would believe the mod itself still functions. I could imagine that it is script controlled and perhaps in large settlements with a lot of scripts running it sometimes isn't loaded correctly.

The load order itself for the mod might still be the same. But apparently you installed/ uninstalled other mods in the meantime and that give the position a different numer. I had it at the last position, too and my first digits where E8. You said you wrote down the prids of your companions. This could have happened with others, too and the first two digits are not the same any more. Maybe you could use "player.moveto AD0035c1" to teleport yourself to her or "prid AD0035c1"and in the next line "moveto player" to teleport her next to you. Perhaps she is simply stuck somewhere. If you still don't see her or the game crashes perhaps try "enable" or "disable and enable" again. Or (but this I would try as the last attempt and make a save before) "recycleactor". This would reset her state as she was at the beginning. Every command followed by enter and without the quotes. In case nothing helps and she is near you so that you can talk to her you could try to unequip her clothings through the barter menu and reequip them again. The same you could do with the the console or the Screen Archer Menu.

Out of curiosity I installed the mod and it works well. Disable/ enable, etc so I can say that at least the last 6 digits of the prid are correct, but when you type in console "prid d40035c1" + enter (without the quotes) and nothing happens or you get an error message it is possible that the number in your load order has changed as the first two digits are the position. Maybe you installed new mods and soupdragon1234 is on the right path. Typing in console "help sarah 4" --> enter (without the quotes) should at least bring up her baseid with a bit of scrolling. Something with .....F99 at the end. The first two digits of the id are the position in load order. If you don't find Sarah with this command maybe the mod is not running correctly, but perhaps you will notice that the first two digits are not "D4" anymore. The syntax for teleporting her to you would be: prid XX0035C1 --> enter (XX = the positon in load order) moveto player --> enter or teleporting the player to her: player.moveto XX0035C1 --> enter Addition: For "placeatme" you need afaik the baseid and you would only get a copy.

Or you have an existing save where she still was visible and can click on her with open console (I would highly recommend to use "Better Console"). So you get her prid and could write it down. Then load your latest save and try to get her back.
