I would guess that was part of the 2015 change at VB where a number of OV inn rooms were changed to standard view, with the result that the excess points in those converted rooms were moved to the OV inn rooms and 3BRs.
Ok...so I am not crazy! We go for a bit every January, I just always book OVIRs 12 months out without looking at chart. This year, I had to cancel our NYE trip, had points in holding, and when I used the holding points for our February trip I had to look at the charts ( we are now healthy!) I noticed the differences.
