Keep interacting with her like like 4-5 times then she'll say thank you the game just doesn't have text to to let you know she's taking each piece individually
Thx & fuck that, I'll reload to my old save & will NEVER interact with her ever again until that's fixed. She still hasn't said thank you even though I already interact with her 4 times (for 4 mats).
Not to mention when you beat a boss of the area to collect mats, the game didn't notify you about the mats you get & that made me thought those were rare drops, which made me fought those guys over & over again. When I finally returned from expedition, I had like 20 of those in my inventory & the game DIDN'T TELL ME SHIT!
Gosh, this game easily stripping away any gamer's sanity. I honestly believe when the dev said someone managed to finish it on Discord is nothing more than a steaming pile of dogshit.
