Lo-Fi Games

I save Kenshi to d: default, this has worked since i bought the game, then either I touched something, or the game decided to store saved games else where.
I can still play the game, as it seems to know where the files are, but it is not showing me where.
I need to erase some saved games as my computer is getting choppy and slow
I have hunted and hunted both d: drive and C: drive , but nothing stands out as saved games
Can you help me?

I'm guessing you're in the experimental build? Recently an option (toggle on by default) was added to store saves in a new location, thanks to some windows issues that were plaguing the old location.

New location is:
C:\Users\<YourUsername>\AppData\Local\kenshi\save

You can also find the location by hovering over the option in the menu, it will show where it is storing them there.
