Bone horror doesn't always follow me

Hey there, I'm a new R/N and have started summoning bone horrors. It seems like about 70% of the time they just stand still after being summoned. Only rarely do they follow me. Is there a trick to this or is it just luck?

My Bone Horrors usually run off and attack anything in sight. I think they only way their going to follow you is if their are no mobs around, but if they see anything... and I mean anything, they will run off anf hack at it. Mine used to attack the seed thingies in pre-searing.

well seeing as theyre death corpses brought to live they might be a lil agressive and attack everything they see while a ranger pet will obey its master and only attack things that its master attacks

They are also rock stupid. If there is an enemy below a bridge that you're on, or on the other side of a wall. They will try to get to it. By running into the wall, or standing where they are and acting confused.

Also, there is the occasional spot, that for some reason or another, looks very nice to minions. They will sometimes just all converge on the same spot and not move. No matter how many you have. And the new ones you summon will just go back there and stand with the others.

The stupidity is how they balance summons. Having 20 lvl 17 things with the AI of a rangers pet would be broken. So they give them the AI of a damp log.
