I'm experiencing a bug on my modded server with the ore node sweetspots.
The sweetspot indicator is disjointed and floating in the air. Unless players are using a jackhammer they are unable to hit the sweetspot of the node until the node has been broken down to its smaller state.

You can see in this picture that the sweetspot isnt attached to the rock and cannot be hit.
We've also noticed the nodes work and look fine upon a server restart, but a few hours later this problem eventually develops.
Has anyone experienced this? Anyone know a cause or fix?
