I can confirm "inventory" (there is some shadiness in what is released and what affects it, ex. searching) was released for me for this itinerary for a 2-3 week period every night at 12CST in the order I described (331 - AAnytime, 329 - SAAver).
Also, not sure what combination of luck took place, but I was very easily able to call into the general line (no status for me) and after explaining the error message I was getting, he put me on hold for about 10 minutes to check with the "reference desk" and then came back and said they combined them for me with no phone booking fees and adjusted the price to the appropriate 30K, no problemo.
Somehow I don't bet it will be as easy next time when I book my return in a few weeks, but one can always hope........
