I have a base on the island, i took al the stuff to SE to complete a wyvern trap, (build a tiny base at red obelisk to store your 200% speed argy or ptera), when you get the milk it spoils fast in SE even with salt, i took it al to the island in my iventory and timer resets when you wake up.. at 20min standard! It lasts 10 hours in a preserving bin with spark and salt on island :) this whas on official a week aggo , got my first dragon and a safer way doesnt exists :)
