In Aurena there is a bookmark problem in UPD 8, It has been fixed in UPD9. So this might be fixed from a Binary Patch. Therefore fix cannot deliver as a single patch.
I was tried to find the exact bug fix for this by referring to the Change Catalog. Unfortunately, there was no fix for it.
My problem is, How can I find the patch, which solves the problem when the UPD was changed?
(Eg: The problem lies on UPD7, and It has been fixed in UPD8)
