Sometimes create 2x2 has different lane counts

Observed this after having used it once before in another scene and had made some adjustments in the lane size in that other scene.

It was difficult to re-create the problem. But, the following worked for me.

Steps to re-create problem:

• Move RoadPoints away from World Origin
• Select a RoadNetwork and click Create>2x2 road
• Select the uppermost new RoadPoint and add some lanes
• Select all the new RoadPoints and drag them away from World Origin
• Select a RoadNetwork and Click Create>2x2 road, again
• Observe that new road has same lane config as previously created road
