When ordering by fixVersion in the Issue Navigator, it seems to incorrectly order by the ID (projectversion.id) rather than the name (projectversion.vname).

To replicate:

1. Create version 1-3.
2. Create 3 issues.
3. Assign version 1 to issue 1 and so on for the 3 issues.
4. Go to the issue navigator and check the ordering of them (may need to modify columns). Example screenie attached.
5. Go back to the project version and change version 2 to 8.
6. Search again. Order is wrong, as per screenie.
