It's the Edge Fade on the Floor Inlay sheet. I don't know what it's doing, but its causing the problem.

If you switch off the Edge Fade the problem is cured.

Edge Fade is usually used for country borders and not much else. Maybe you wanted an Edge Fade, Inner?

It works in most cases where the drawing tools have been correctly setup to fall on the 'FLOORS*' sheet. The asterisk is a wildcard that allows this to happen. The only proviso is that you do need to have the chosen 'FLOORS Temple floor dirt' sheet picked as the active sheet before you start to draw.

A fantastic set of maps. Thanks very much, Ricko :)

If you right click the fractalize button there's an option to convert Straight to Smooth. You can go back and forth with it. You might want to fractalise it just a bit more right now before going smooth as that will give it a more wiggly appearance. Don't go overboard, though. No more than 3 hits with the fractalize tool at it's default setting. Then go smooth and see what you think.

Save a copy first ;)

The problem with your original file was a corrupted sheet. I also got an out of memory warning the first time I tried it. Then I discovered there was a problem with the SYMBOLS sheet and created a new one. Once I copied everything across and deleted the original SYMBOLS sheet everything worked ok.

Your system has plenty of memory and should cope ok with 40 million PPP on export. How does it do with the repaired map?
