PFlow-ABurn Operator bugged in Max 2015?

[shawnolson]

Has anyone noticed this problem in Max 2015 SP3 using AB: Very often you cannot drag a PFlow-Aburn operator to an event. When you do, very often the operator creates a scene node but the operator is missing from the event or from particle view; however, the operator params are sometimes available in the Parameters tool when selecting other operators in the event.
