Terrain deform: Work on client & server. But not dedicated!

So, I've had terrain deformation for both client and server working for quite a while. Or, at least it appears to work - but there's a snag. I finally got around to setting up a dedicated server for this beta (before, I was using a non-dedicated server so I could keep a watch to see when people popped into the server to play, and quickly join 'em.) Now that I've got all my dedicated server goodies set up on the script side, I start testing - at first, everything looks ok, until I dig a little deeper.

For some reason, this works fine on a non-dedicated server. On a dedicated server, the collision mesh for the terrain gets all sorts of wonky. If I raise an area of terrain up, and a player lands on it later (only happens with randomized terrain generation - another good use for this code) they just fall right on through to the original terrain height. (But, displays just fine on the client.)

(Go ahead - make fun of my TorqueFu here ;-) I had an issue with detecting the server -vs- the client version of the terrain, so the same code got wrote twice, once for the client and once for the server. Among other hacky things about this code. Sleep depravation and coding are a scary mix :-)

ConsoleFunction(setTerrainHeight, void, 4, 6, "(Point2F pos, F32 height, F32 width, F32 deformType)")
{
	Point2F pos;
	float height;
	float width;
	float deformType;
	Point2I gPos;
	Point2I minPos;
	Point2I maxPos;
	float currHeight;
	float currentHeight;
	float newHeight;
	dSscanf(argv[1], "%f %f", &pos.x, &pos.y);
	dSscanf(argv[2], "%f", &height);
        dSscanf(argv[3], "%f", &width);
	dSscanf(argv[4], "%f", &deformType);
	TerrainBlock * terr = dynamic_cast<TerrainBlock*>(Sim::findObject("Terrain"));
	Con::printf("In terrain deform.");
	if(terr)
	{
	    Con::printf("Ok, there's terrain.");
		if(terr->isServerObject())
		{
		    Con::printf("Yeah, it's a server object.");
		    if(deformType==1)
			{
				const MatrixF & mat = terr->getTransform();
				Point3F origin;
				mat.getColumn(3, &origin);
				F32 squareSize = (F32) terr->getSquareSize();
				F32 halfSquareSize = squareSize / 2;

				float x = (pos.x - origin.x + halfSquareSize) / squareSize;
				float y = (pos.y - origin.y + halfSquareSize) / squareSize;
   
				gPos.x = (S32)mFloor(x);
				gPos.y = (S32)mFloor(y);
                
				terr->setHeight(gPos, height);
				minPos.x = gPos.x - 2;
				minPos.y = gPos.y - 2;
				maxPos.x = gPos.x + 2;
				maxPos.y = gPos.y + 2;
				terr->updateGrid(minPos, maxPos);
                                // This updates the collision mesh
                                // Works fine on a non-dedicated server.
			}
                }
	}
	else
	{
	    Con::printf("Umm... it's not on the server.");
		TerrainBlock *terr = dynamic_cast<TerrainBlock*>(gClientSceneGraph->getCurrentTerrain());
            //.... same thing happens here as above ....
        }
}

You can see the stuff that's supposed to spew to the console for debuging purposes. On a non-dedicated server you'll see:

Ok, there's terrain.
Yeah, it's a server object.

On a dedicated server you see... exactly the same bloody thing. Nothing crashes, nothing looks like it goes wrong. It just doesn't do it's thing.

This is the only thing holding up Beta 3 of Trajectory Zone now. I'm loosing hair by the hour tryin' to puzzle this one out. Help? :-)
