say something regarding changed decorator events… Please 
[/]
According to our bug reports, only one decorator has been resolved for 4.7: UE-7870 BP-implemented BT decorator issues with 4.6 to 4.7 upgrade resolution had note: “Added a transition API to mitigate fallout after a drastic change in BTDecorator_BlueprintBase’s API”
Is that what you are about? If not, I’ll see what else I can find out.
