Loss of functionality

I felt this the best area of the forum to post this.
I have noticed over the last couple of days since SU3 that there is a loss of some functionality in some aircraft.
Aircraft that had for example prop feathering no longer seem to have that function ie. the Caravan and Kodiak for instance along with others. These aircraft both had this function in SU2.
Controller settings have not changed (in my6 case the Bravo).
Seems to be the ongoing problem of fix one thing break another.
If anyone has this working in these acft please let me know you settings if using the Bravo.
