In my inventory I have no empty place and I am at second floor in a building. so I want to put gun on the ground and take soda and drint it. when I do that my gun or any item dissapear. I can't take it again and not showing on tab menu. I need to go down if it isn't there again I must go second floor again, then I can find it. Sometimes item won't stay on a box. it go down in it and I cant find it even not clicking it.
