Missed side chain sends

Sometimes when I activate a side chain key in a plug-in, Cubase doesn’t show its send in any channel.
I have used Cubase since 7.0 version and such issue has been happening since then once in a while.
These are the plugins with which I have had this problem:

  • Cubase’s Compresor
  • Waves In-Phase
  • Fabfilter Pro-Q2
  • Fabfilter Pro-C2
  • Fabfilter Pro-G

The problem gets solved restarting the app. It’s annoying. :smiley:
