Hello, i am using 1.0.2, tested 2.0 beta, but still have the same problem. I have the following structure of articles:
1. Advertisement (top category)
1.1. Cat1 (subcategory)
1.1.1. Cat11 (subcategory)
1.1.1.1. Item1 (Item)
1.1.1.2. Item2 (Item)
1.1.2. Cat12 (subcategory)
1.2. Cat2 (subcategory)
1.3. Cat3 (subcategory)
... and so on ...

The problem is when I go to any ITEM, my breadcrumbs module displays the path as follows:
Home >> Advertisement >> Item1
loosing any categories on its way.

But if i specifying (typing manually) `&category=5` in the URL string - everything is ok.

How can i fix this?? Thanks for your attention!
Paul

Edited: Also, when i create menu item for root category (with category listing layout), it does not include any categories ids, thus native K2 breadcrumbs are not displaying at this point.
