I have a idea that might be a lot easier to make : when a player drags a dead/uncticious body or when you whistle to dinosaur to follow it does so what you could do is add that whistle element to a dead body and up the range to like 500’000 so when you spawn back in the dead body with your items ether moves towards you you could also add a feature where it moves at super fast speeds so you could wait at your base while your dead body is coming to you when it arrives (if it does) you have got your items
It not exactly a Keep Inventory mod but it still would be awesome o have the above idea as a mod
Use at your own will I won’t be making this so I’ll leave it to you
