Unfortunately neither of the broken saves load in the new version. Should I upload copies of them so you can look at them? I can also upload a copy of my custom map (even though it's just Cradle set to 50x50) if you want.

The map: https://download1072.mediafire.com/thew06r98umg/jr7ln87sdhwivyf/atma_maps.zip
Yes, there's only one map despite the filename; ideally I'll make and add more maps, but I'll have to study what we have now to make maps that work.
