Games not saving on local multiplayer

I play a local multiplayer game with 2 other people. We've played numerous games together on this version of bedrock and each time the games do not save. The games take hours to save but we have to close the application due to overheating and time crunches in our personal lives. There is no autosave feature for us to go back a few minutes, instead we lose everything we worked so hard to build. We've tried saving every few minutes, each player leaving before saving, and nothing seems to work. We've lost several hours of work each time.
