_Deref autocomplete broken?

I know _Deref is a private formula, I’m using it at my own risk.

Noticed today that autocomplete no longer works for _Deref, for example:

_Deref(myRow, SomeTable.ObjectColumn). // <- only globals shown in autocomplete

Even for built in types like date where you don’t need to rely on autocomplete it shows an error (although the formula works).

_Deref(myRow, SomeTable.StartDate).WeekNumber()

Can someone else confirm they are seeing the same behaviour? I want to check if it’s a glitch on my side, or if it’s time to stop using _Deref.
