You're on a Mac, right?
So there's this weeeird bug...
Basically I can't open Finder from within the game right now, but the good news is that your awesome GIFS are safe and sound! (whew!)
Just navigate to:
/Users/User_Name/Library/Application Support/Haven Made/Warcube/gifs
Oh and one more thing!
If you're not already, you should join the Warcube Discord! It's full of a bunch of nice, cool people :D
