              Any Idea what is happening with the height map file. I installed Beta 2 but it is the same thing

                That's a long bed! My guess is that the large number of points along it (27) is causing the file line length limit to be exceeded. For now, try a larger grid spacing to reduce the number of points along the X axis.

                    Fixed in 1.18beta3. Max number of points along the X axis is 25 in 1.18beta2 and earlier.
