If you plaing on a emulator it is very possible that visual bugs may happen or things not workking. I never used that emulator so I don't know.
Easist thing definitely would be to look at your save file to rule out if it is the emulator or a actual bug.
Feel free to send upload the save somewhere and send me a link so I can download it, when I can take a look at it. Google Drive, etc. And sorry to hear that happened to your pc.
