Huh, that's odd. I'll need to look into it! I haven't heard of anyone else running into those issues, so I wonder what could've happened. Thanks for bringing it to my attention! I'll try and get a fix up as soon as possible!
EDIT: I have looked into the issue and I have no idea what is causing it as everything looks fine on my end. I will add the map70.json file in the download folder, however, and that will hopefully fix the issue.
