I've summoned my skeleton repeatedly. It disappears after 30 seconds. Just goes poof. Mind you, it doesn't move out of the radius... it doesn't really have a chance to move more than a couple of steps before it simply unsummons. Clearly this makes the doll useless. I've asked on the Hints forum, and learned that they are supposed to hang around indefinitely unless they are killed or leave the area they were summoned in. So what could I possibly be doing wrong, or is this a bug that others have noticed? I'd appreciate any thoughts or assistance on the matter.
