Hello. I have this problem. I model objects in the program, everything works well. Then I save the project and close the program. Then when I run the program and open a saved project, some objects in the scene change spontaneously, and some objects are simply deleted. Can you tell us what the problem is and how to fix it?
Without further details, like example scenes and the exact steps how to reproduce this, there is no troubleshooting possible, but it's not the default behavior.
Try to delete history before you save a Maya scene.
