We're using the Project Backlog plugin for our projects. Somehow we've gotten into a state where there are two cases with one order number, and an order number with no case. For example, in a search for backlog:"1.." ordered by the Backlog column, the backlog column will read 1, 2, 3, 4, 4, 6.
If I click the backlog order number for one of the duplicates (e.g. the second "4") and specify the missing order number ("5"), it instead updates the first duplicate's order number to "NaN" and leaves the second as "4". However, when I reload the filter from the server, it shows that it successfully renumbered the case I modified (to "5"), but also renumbered the other duplicate (the first "4") to still be a duplicate (it becomes the second "3"). If I continue to edit the cases in turn, eventually I end up with a case in the backlog numbered 0, with no case #1. I can then change that case's backlog order to 1 to remove the kink in the backlog order.
The same occurs whether I edit it in the list view or edit the case by itself in its own page.
Version 1.2 notes that all known order corrupting bugs are fixed, but we are using version 1.2. Is there some way to diagnose or repair the backlog order should this occur again?
