When I use move objects on and try to move my sims to a different spot in the game, they always end up in the floor.  Example:  I had my sims swing on the swing, when I tried to move them after I got them as high as I wanted them next to another sim that was using the kick bag so it looked liked they were kicked, they sank down to the ground. Part of the body above ground and part under.  Can anyone help?
