The most likely explanation would be it got stolen.
People can steal from your inventory even when you are offline, if they have access to your homestead (leanto or claimstone).
So if you do not have walls or locks on your gates anyone can check your inventory when you're offline and take whatever they like.
To check if that's the case, make sure you have tracking on and check if there are any pink signs of evidence at your homestead. You might need to reload the area to make them visible, to do that just go inside any building/mine and back or run past rendering zone and back.
