Thanks, that seems to work.
Another problem. After doing a bit of work on my map, I saved it and then reloaded it. It is now a completely randomized map (like if you selected new map, and did not hit the blank map option). The terrain I created was gone.
I did a few tests: I created a new blank map called 00 test1 and created a smiley face with the terrain. I saved, got out, reloaded the map: new randomized map. I tried it again without the override old copy button checked, same result.
Anyone else have this problem?
