I'm confused. Awardwallet shows my latest activity on 31/12/2016 and says my points will expire at the end of the month. Went through the 24-month history on Hertz's website and it doesn't show anything either (only a few rentals with 0 points). My points are still there though (lucky enough)

To stop them from expiring I tried to make a points reservation in the future (compact car - 1 day) but I always get an error that I don't have any points. In the end I tried to make a reservation for the day after tomorrow and that works.
Not sure what to think of this: It seems it's no longer possible to make point reservations after their expiration date.
(just not sure why they haven't expired yet, maybe you get a 2 month grace period?)
