Minor question. I know the Sandy sidequest is how you get Waterium-Z, but I forgot to deal with it before Post-Game. She's not where she should be at Malchous Forest. I saw on another topic that this issue was seen as a bug and fixed. Do I just need to get further into the post-game before that triggers again?
Edit (Maybe a spoiler re: post-game. Not sure if I should cover it in a spoiler, but I'm doing so just to be safe):
