Hats Mod for 1.7.10

I have an issue where when I leave my world, my hats get deleted and I have to hunt for them again, but when I use the Hats stand mod, they stay on the stand. I don't know what I did wrong. I am using the Crazy Craft 4.0 modpack that I ported from the void launcher to forge. I would love to have any feedback from anyone because this is really getting on my nerves.
