If you are in an auto-run situation (i.e., if you have clicked somewhere on the screen or you clicked the "go to destination" arrow) and go to interact with an object, you pause temporarily, until you have finished your interaction. This is fine behavior in most situations, but if you go to meditate, you will immediately start running, breaking the meditation. This is not good behavior. When you begin meditating, it should clear the movement queue, so that if you wish to move (and break your meditation early) it is intentional.
