Objects change transform when loading scene

Hi. While working on my 3D models, I set the transform of all my object to be in a specific location. I save it, everything is fine. However, when I load my scene the next day, the transform of many of the different pieces of my model moves/changes. Sometimes the scale of the object changes to be really small, other times a piece will move like .07 meters on the y axis. So I have to spend my mornings moving the pieces back to where they belong.

Any help resolving this would be greatly appreciated!
