I've recently encountered a part of the ground that just can not be minded or manipulated. Was flattening the ground out, and building a mote when I found this huge section of earth that absolutely refuses to change. Wondering what that is all about.

The terrain uses a height map and can only be altered +/-8 meters from its original height. Allowing more alteration would double the amount of data each terrain point takes up and would have a quicker negative impact on performance. It would also be more performance demanding as any alteration of terrain would have a larger radius of impact, exponentially so, as alterations don't just effect that point but radiate outwards. So it would significantly decrease performance.
