Reassigning a send to a new auk track

Regarding 2017.01 fixes, CWK says:Resolved a crash when reassigning a send to a new aux track.
Yesterday I checked " a snare with a better gated reverb" as it was described on Friday's tip of the week #64.
At the end of tweaking, when everything is accurately done as explained on the #64 tip, and I want to listen:...sigh...
Sonar crashed as chashed 4 times on 5 until now when I apply this technique.
So for me the issue is not solved.
