I have an SpriteAtlas folder with all the altas inside this folder. The problem is that sometimes an accesorioAtlas.prefab that I have disappear so I delete the accesorioatlas.Data to create the atlas again, but when I deleted this, all the SpriteAtlas folder are destroyed!
So I have to create every atalas again, and all the spirte that has a reference to the atlasCollection are lost too.
