Gerrit hooks sometimes doesn't update bugs status

I've encountered that a few times today, here's on example: https://gerrit.ovirt.org/#/c/70701/ Patch Set 1: Verified-1 - Update Tracker::#1413961::OK, status: POST While the tracker was indeed added, you can see that the bug was not updated to post status After the merge: - Update Tracker::#1413961::OK, status: MERGED - set_MODIFIED: OK And the bug was not updated to modified status Thanks in advance.
