dUPLICATing maps - packet corruption occured.

conf3derate

I am not able to finish my quest in the foundry because I get a packet corruption error when I duplicate maps and try to save them. Have been working on this quest since 05/11/2013 and about ready to throw in the towel and wait til something else comes along to develop a world in.. Don't see myself wasting anymore of my time trying to get things here to work...
