We can't bring back the previous version of the texture (material) using 'Ctrl+Z' when we use object attributes
It seems configuration of objects using **control=Combo** in attributes with **expression=setObjectTexture(Material)Global** causes errors when we use reverse
```
=========from .rpt when I try reverse Coffin_02_Flag_F texture:
21:01:04 Error in expression <_this setObjectTextureGlobal [2,_value];>
21:01:04 Error position: <setObjectTextureGlobal [2,_value];>
21:01:04 Error Type Number, expected String
```
