Locked Out of 20 Hours of Progress

[I<3YogaPants]

I bought this game on my main Steam account and used the Family Sharing feature to play it on my second account (this one). At some point in the last 48 hours, the developers disabled the Family Sharing feature for this game. What's worse, from what I can tell, the save files for all users are combined into one file at the location below.

C:\Program Files (x86)\Steam\userdata\[Steam ID]\2322560\ac\WinAppDataLocalLow\yoogames-hd1-steam\LoveIsAllAround\SavesDir

This means there's nothing to copy/paste from file to file so that I can access my progress on the Steam account that actually purchased the game and I am effectively locked out of my 20 hours of progress. This is unacceptable. If the devs never intended for the game to be accessible via Family Sharing then it should have been disabled at launch. If I had know this feature would be disabled two weeks after release I would've bought the game on my second account or just not bought it at all.

If there's a way to gain access to my progress on my main account, then please inform me.

Developers, if you won't re-enable Family Sharing then contact me so that we can reach some kind of agreement. Otherwise this thread can just be a warning to any prospective purchasers who use the Family Sharing feature.
