I seem to be having an issue with one of my characters. Her first water skin randomly disappeared from her inventory with no obvious reason. So I bought another and also a couple of spares just incase one disappeared again (it being that the initial disappearance had occurred quite a way from a water source and caused her some issues!). Anyway, fine for a couple of in game days, then both spares disappeared.
Any suggestions for the cause? Is there something really obvious I'm missing.
