I'm wondering if anyone else has this problem, even after reinstalling the mod, copying and pasting the data pack as well as the data pack in the compatibility patch, the game outputs an error that replaces all the saves in the save folder with the ".anothergame" extension. I've tried renaming the extensions, copying the save folder and replacing it whenever the error happens, and whatever else came to mind but to no avail. Did I miss a step during installation?
Oh also forgot to mention that I've run into this same problem with 1.6.4 however renaming the saves once usually fixes the problem, but for 1.7.0 it doesn't seem to work.
