I wondered if anyone else was having this error.

I noticed when I played the game recently that my affinity with Gregor had entirely disappeared (I had gotten him to Heart Circle previously).

I ended up buying the game on Steam as well and when I played it from there and started a new game working for Gregor does not increase my affinity with him at all.  Is this something I can fix?

Hello, if you just started a new game, it's normal you can't increase your affinity with Gregor. You first have to repair your house to unlock his affinity.

If there is something wrong with your save, you can send us an email at grizzlygamerstudio@gmail.com

Maybe we'll be able to help you.
