I thought that it might be like that.Do you ever find that you have too much wt under a base? It happens, each base is different and max's out at different weights. Can you wt it to the point it will not move or be moved? I'm sure there is a minimum movement rule otherwise it would be considered an immovable object ala magnet and Holding could/should be called. then you may run into the number of magnets rule if it will not be moved. Most likely. also I know you cannot really put a magnet on a ttc base or so I thought--LMK STT See previous post.
