So, this year:

64 nights
​122k qualifying points
Completed the "10 nights to retain diamond", but would have still scraped it on points.
6 milestones redeemed.

Still not sure if the milestones are continuing. Can't see anything on the website, although its saying I need 6 more nights in the calendar year for the next one.
Something tells me I might not get 6 more nights assuming the calendar year ends today
