This was my scenario about a year ago. Had a reservation for 7 nights but ended up needing 6 due to my spouse's work schedule change. Check-in date was more than 61 days out. Spoke with with agent thru online chat describing what I needed. They obliged and edited the reservation and the 1 night's points went back to my account. End chat. Checked my account a few hours later, the 1 night's points that went back into my account but was placed into a 60 day holding account. Immediately called MVC and inquired what my situation was. Agent explained that changing (shortening, in my situation) a reservation after a certain "cut-off" date will cause points to go into holding. I wasn't happy with that answer due to the fact it was more than 61 days to check-in to begin with. Agent had to escalate to upper management because I wasn't satisfied with their answer (and after a lot of back and forth). End result, management ended up removing the hold and gave me one year to use those affected points. Fortunately, I had another trip that I could re-allocate those points into so I was satisfied-without telling them I was. In short, in my haste to edit my reservation, I took for granted what I thought I was expecting without verifying the true details (my mistake). It was only by checking my account later that I discovered what had actually happened. From that point on, if I have to edit another reservation (which I don't normally do), I would cancel first and then re-book the same (assuming there is inventory). Otherwise, I would have to speak to a live agent, ask what would happen to the points if I continued and then verify details afterward with them on the line. That was my scenario.
