Well after messing around with things I suspect the problem occured because Atrocities saved the SectTypes.txt using SE4Modder. This causes some of the items to be saved in a different order. (ie all planets get saved first) This does not seem to matter at all if you play a game and generate a new map but it would appear the saved maps must have a SectTypes.txt file that is exactly the same as when the map was created. Who knew!? I haven't tested it but I assume a saved map would work with a new SectTypes.txt as long as all new entries were added at the end of the file.
