The problem for us is that we do not create a single map. As there are no good tools to edit maps, we create up to 40 maps in the 6otM creation process and then test them to select the save we want to use. I do not know how to extract the map seed information once the save is selected and keeping track of them all is certainly an issue. Plus, don't you get the correct map using map seeds but the civs are not always placed in the same spots?
It would be better if we could make saves available, but I do not know how to do that either. How do you upload saves on a switch and where do you get them from? Can you download them from this site?
