BackPack leaving this earth atmosphere

Hey I love playing township tale but a glitch happened recently and my backpack is just straight up gone from the moment I picked up one of those big swords and put it in what I thought was my backpack later to my surprise the backpack was gone and replaced by the sword so I went searching for the backpack everywhere we went and still could not find it. I think they should have a button or a setting
