@Gordon Fecyk @GregroxMun I'm having a very similar problem to @Fireheart318, though in my case it's Laythe that's not working (though I've only seen Duna; there may be other planets that don't work). This is on a fresh install of KSP 1.3.1 32-bit, with no mods other than ASP and its prerequisites.
Here are the logs: https://www.dropbox.com/sh/wlymdmbzb2bqwb6/AABp8JxTImrYzo3h3bpG-kz8a?dl=0
