Unet Client child object not rendering

Hi I have a very strange problem. I have a fireball that has a parent object which contains the model for the core of the fireball the trail for the fireball and the explosion. The problem is when I spawn this object across the network the model for the fireball is not visible on the clients even though it's mesh rendered is enabled. Can someone tell me why this is happening? I don't see any reason why this object wouldn't be visible. The motion tracking is not the problem because the fire balls trail is in the right place as is the explosion. If anyone could shine some light on this bug it would be a huge help.
