MainType 12.0 changes font file's date and timestamp when moved.

Bug: MainType 12.0 sets font file’s date and timestamp to current date/time when moving a font to another font folder.

This makes it more difficult to manage font files outside of MainType, e.g. in relation to backups of fonts that one is currently “cleaning up” in MainType.

MainType does not rely on original font files as it just takes the font from the internal database. It is possible you have multiple copies of the same font, with different file names and different timestamps.
