VedaDalsette,

One of DAZ Studio's content packages overwrites Poser's magnets obj files. I had the same problem that matches your description. I was able to restore Poser original files by copying from another version of Poser that was already installed.

The zone prop is the ball at Runtime:Geometries:props:ball.obj. See if something has messed with that.

By default, Poser installs obz files (They are compress obj files). If there is an obj and obz file, I do not know what one Poser will use.
