Cubik Studio

I set tint index 0 for a plane so it got green. Then I made a mistake and pressed strg+Z and the green went away...

And when I cloned an element that ha a specified tint index (and was green) the duplicate wasn't colored but the tint index was specified.

Can you provide a step by step guide to reproduce from a fresh Cubik start please?
That may be a bug

Okay:

1. Open Cubik
2. Create an element
3. Set tintindex for any face
4. create another element
5. press ctrl+Z

-> Tintindex is gone
