I have a trip planned for August. I booked some of my nights using my 2018 points and my borrowed 2019 points. Since my use year is April I had one night not booked because I did not have the points to cover it. I had a waitlist that I had forgotten about but got an email today that it was fulfilled. All of my points for 2019 are now gone but I should have been 16 points short still. How did this happen? Did they charge my card (I don't see any charge on my card yet at least)? Since my reservation is after my use year will it get pulled from 2020?
