Changing model corrupts instance when loading old model

[c0diq]

1. Create a class with 2 strings instance called text1 & text2.
2. Save instance
3. Change text1 name to textNew.
4. Try to reload instance.
5. TextNew will be null (normal) but text2 will be an instance of a placeholder instead of the original string.

Note that I use HRCoder in conjunction with AutoCoding and BaseModel in this example.
