I have to assume at the automatic backup is suppose to be an auto save feature, the settings for the time say:
"An interval in minutes, at which the project is saved to the back up folder".
but the project isn't saved. Currently, all this does is copy the version of the project which is in a directory (C:\Users\BC\Documents\Spinestuff\myproject.spine) to the back up directory, which means the backup directory has thousands (?) of versions of the same file. What use is it to have the multiple copies of the same file in the same directory? If that directory corrupts, all the backups have gone.
