Contidional nulls query broke in latest update

[moody31415]

I have a query that just broke unexpectedly recently after presumably a powerbi update.  You can see the condition that broke in the below image:

= Table.AddColumn(chose2, "NextDate", each if [nd2] is null then null else if [nd2]  >= 2 then [NextDate2] else [NextDate4], type date)

It seems that "if [nd2] is null" is causing an error to occur, instead of evaluating properly, when the input is null. This worked successfully previously.
