Two things. If you are using RunUO, try [unfreezemap and then [clearfacet. This will delete ALL non-player mobiles and items from your facet (I had a similar problem and this got rid of the items). Make sure that the "Is Player" property on your mobile is set to "true", otherwise it will delete you, too! After doing this you'll want to replace your statics files with the ones you created in Dragon again and reload everything.
Also, try replacing the diff files per this post:
