Crashes have gotten more common for me as well, I think the reason is because of the wings. (Maybe your computer cannot handle the extra stress, mine would crash randomly when Feral Heart didn't even have wings.) Now, I'm not against wings at all, I think they are a good addition to Feral Heart, but if your computer is like mine it will cause more lag and that can make your computer act odd. (Example: freeze, screen go black, Feral Heart doesn't work,) all of which have happened to me, so maybe that's what is happening to your computer as well. To reduce lag, and this may help your crashing problem, I'm not entirely sure, you could turn down your view in-game, and could also turn the reflection off of the water. You may also want to check to see if you have any saved screenshots in Feral Heart's folders, because if you have too many you can lag. Hope this helped.
