autoflanger problems...

On a coaster im currently finishing up, i have done about 50% of the the supports and I wanted to see what they look like so far with the flanges added. So I used the autoflanger and it keeps making the whole ground under water

Is anyone else having this problem?

I have the same problem too, although I am even getting this problem without using the AutoFlanger - Alot of the NL tools are having weird effects on 1.5 tracks.

Here's a workaround that might help: Open the track in the editor, go to terrain settings and click on "default settings". Terrain should look like before now.
