As far as I can tell those of ours that did not work now do.
Now to the interesting part:
Ticket numbers for our two partially reissued tickets now show entirely with the partially reissued ticket, not the original 014 one, just like on aircanada.com while on the Saudia web site, only the reissued part shows that non-AC number, the reminder of the trip is under the original number. Also, still shows legs in the past, with UN for a non-AC flight which we did not take, and TK for the one we actually took. AC flights in the past (and obviously in the future) show as HK.
Maybe the TK is why it seems impossible to get Aeroplan miles credited...
