Piper Hostil.

[Solomon🧉]

Estaba haciendo una de las misiones de mortaja plateada y sin querer mate a un civil con una granada, la cuestion es que Piper me empezó a atacar y me salio un mensaje para enviarla algun lugar, lo hice sin pensar y ahora cada que voy al Santuario esta ella y me ataca! no me deja modificar armas, nada, es una pesadila, hay alguna manera de quitarle ese efecto? o por lo menos trasportarla a otro lugar?

How long have you let her be hostile?

Because the MOMENT that she turned against you, you should have quit the game and loaded an earlier save to fix the problem. You likely were making her angry a lot, because to turn someone hostile that was your companion like that is VERY HARD to do.

If you look at Piper's information on the charts on this page, maybe it will show you what you've done to make her angry enough that she will then turn on you.

It became hostile after I killed a peaceful npc by mistake, I moved it to sanctuary and didn't go back there, I really forgot about it and just kept doing quests and exploring, I have no save from before that because I overwrote it, now I can't upgrade weapons or anything in sanctuary, that's where I have all my junk.

If you still have control over Sanctuary, you can use the command "tdetect" to disable AI detection completely and get your junk out of there. Use "tdetect" again to re-enable AI detection after you left Sanctuary with your stuff.

Npcs usually calm down after a while. A week should be enough.

After you complete the quest "Reunion" Piper pops up in Diamond City in Valentine's office and is ready to accompany you again. This would fix the previous behavior, unless she is still mad at you.

Good Luck.
