Hi Jo, I really don't know whats causing the problem. Today was the first time it had the problem since May 11, 2009, 09:35:14 PM.
Um, I tried saving it here:
C:\Users\Ian\Documents\ian projects\terragen projects\prairie\prairie_1.tgd (i typed the _1, didn't use save incremental)
This was the first save with the filename prairie_1.tgd
I have uninstalled TG2 completely, reinstalled it, and am re-rendering my scene, which by the way saved fine both after I adjusted the quality of the render and after i adjusted the sun elevation. I have absolutely no clue what caused the problem. I'm leaning towards my system though. maybe too little memory or something of that nature.
Subsequent saves with prairie_1.tgd were fine after doing the uninstall, reinstall.
I don't think the camera issue is your department Jo, but it might be. If need be, I can open another topic.

As for the camera placement issue, when I adjusted it and saved the file it kept the camera position fine, but the original (prairie.tgd) lost the values and placed it some distance from where it should have been.
