Odd behavior on file modifying with Inky

Hi,
I am using Inky (0.61 I believe) and noticed an odd behavior. When I make a change to an ink file and do a save inside Inky _all_ ink files in the same folder update their date of modification to the same timestamp! It is as if changing one ink file caused all of them to be touched. Strange.
For me unfortunately this is a bit more than an oddity. I use date of modification to decide when to automatically inklecate out of date ink->json pairings (i.e. json has fallen behind the ink). Therefore this odd behavior causes me to inklecate more often then I need to. Mild efficiency issue.
I am on windows 7 64 bit.
