there is a bug that if you have items inside a chest, plant potatoes, leave water on a purifier or leave food on the cooking station and exit the game all the items are gone when you come back
I'm on windows and I had this happen as well. Saved and logged out of the game, came back later and all of my food that was cooked on my fire pits were gone and all of my boiled water that was sitting on the water purifier was also gone. It'll be a hassle if I have to keep all of that in my inventory before logging out if this isn't a bug.
