You guys!
You can get around the save-crashes-the-game issue, and the orcs-catching-you-crashes-the-game-issue by:
Open the directory C:\Users\(your user here)\AppData\Local\
Find Heavy Hearts. If it was crashing for you before, rename this something else. (like: oldHeavy Hearts)
Then play 0.3.2. This will make a new Heavy Hearts directory there, with the new files it needs.
I guess the ultimate fix would have to create a new subfolder for each version.
