Why?

Ever wonder why you can't find a story you know that you favorited and bookmarked for the foreseeable future? Me TOO! And I think they got banned or something, I don't remember who they were, and I know I talked with them before, and now they're just gone, they had a good story that I read multiple times waiting for the next chapter. Today was a day when I decided I want to check on the story and now it's just gone! I don't know when this happened, but I'm asking anyone if they know why these things happen. Maybe it was just made private, but the fact you can't find the person who made it is more concerning.
I can only remember what the story was about. It was a samurai/ronin character with blonde hair and had magic swords, she kills sombra and the becomes ruler of the crystal empire, they have a golden age and stuff, while the 'main characters' fight over who rules them and yada yada yada. The last chapter I remember is them having diamond dog problems. If anyone remembers this story and or finds let me know. I'm desperate to find it at the moment.
I've went through my favorites and bookmarks and even check who I was following and email through comments.

UPDATE!

Multiple stories are missing on the site! I just found out that 3 other stories I KNOW existed are just gone.
