FlyerTalk Forums - AA RTW re-issue; should I be concerned?

Back story: I purchased a DONE3. I called to make a change and worked with an iffy agent at AA's RTW desk. She collected my credit card number and told me the ticket would be reissued; my itinerary online was updated to match my new flights. I was promised but never received an emailed itinerary. The morning of my initial outbound flight (three weeks after the reissue), I called the EXP desk to confirm seating and check loads and was told that the ticket had never been reissued. I was transfered to RTW where an agent I've worked with before--an experienced one, I knew--said that it had been improperly queued for reissue; he had it taken care of manually while I was on the phone. I received an email showing the reissue.

Now, I'm in India. I'm shortly flying back to the States via HKG on CX and called yesterday to RTW to make a routing change (BOM-HKG-LAX-SFO vs. BOM-HKG-SFO). The agent--a different one--took my credit card, updated the reservation (it's correct online), and told me it's been reissued (I was on hold 10 minutes or so). However, I never received an emailed receipt of the reissue. The flights are soon, and my next checkin is with CX.

Should I be concerned that again this was improperly reissued? Is the worst case simply that I'll be stuck with the original routing (longer hours, fewer miles)? Advice welcomed! Thanks.
