"This project has been recovered" message. Why is it trying to do me a favor? ;)

So, I've been randomly seeing this message more and more over the last week. I'm on a Win 7 machine, saving to a network drive. I'm using Storyline 2. Update 10:1607.1221.

It's the weirdest thing when it happens... it's almost like a temporary version of the file is trying to fix itself. I was freaked out the first time it appeared and decided to close the window and try again. Opened it again: NO ISSUES. 

But, it keeps doing this same thing... I open up a file that I haven't worked on in a bit and it says it recovered it for some reason. I close the file, re-open and the 2nd attempt is just fine. 

One of the attachments I'm including is a screen-shot of the most recent one. It actually blended a couple of separate (but related) files together - part 1 and part 2 of a .story file.

It's entirely possible that this was triggered by converted Storyline 1 files, though I'm not certain. I am re-using a template over and over (didn't want to insert logos and buttons again and again), since I'm changing the title and recorded content only. But I'm not 100% sure that the original template was a conversion or not.

Any ideas? Thanks, in advance, for any guesses. :)
