Looking for some guidance.

I had the following award route booked for my wife and I:

MLE-CMB 20:45-22:40 (Biz on UL)
CMB-HKG (+1) 00:55-08:40 (Biz on CX)
HKG-LAX (same day as CMB-HKG) 16:35-13:05 (F on CX; wife on separate F flight same day)

It looks like CX cancelled the CMB-HKG flight on my (+1) date and moved it to the same date of my MLE-CMB flight, but earlier in the day!!! My route, in chronological order, now looks like

CMB-HKG 00:55-08:40 (Biz on CX)
MLE-CMB 20:45-22:40 (Biz on UL)
HKG-LAX (+1) 16:35-13:05 (F on CX; wife on separate F flight same day)

I called CX and they said I have to call AA. Called AA (on the phone now) and they are looking for any other availability to get me from MLE-HKG in time for our F flights. Has anyone ever had this happen where a mid flight got cancelled and rebooked to a time that throws off the whole line of flights?

If I HUCA with CX enough times, is it possible to get someone that can help me, or am I stuck with what AA can do on their end (i.e., limited to whatever availability the AA agents can find)?

I know it is highly unlikely, but is there any way I can get CX to get my on some MLE-[x]-HKG flight that may not have business availability for rewards because they cancelled my original flights? Or with awards is it basically a "too bad," response?
