There is an autosave option in OpenToonz' settings. I have now turned it on.
Edit: I've gotten some comments informing me that my experience isn't as universal as I thought it was. Even despite the crashing I've dealt with, I still highly recommend OpenToonz. I just made this as a funny way to vent my one frustration with it.
