Crash when removing Voxengo while playing

I can reproduce this crash every time I have the transport playing, and remove Voxengo Elephant or Voxengo EBusLim from the montage master.

The strange thing is that it only happens when I remove it using the plugin window chain by right clicking and choosing “X None”. If the transport is stopped, or if I remove the plugin from the effects tab there is no issue.

The issue is just when removing a Voxengo plugin from the plugin chain window when the transport is playing and using the right click/none technique.

Other plugins seem to allow removing while transport is playing by using the ight click/none option in the plugin chain window.

The crash happens even if Voxengo is the only plugin in the chain.

WL 8.5.10
OSX 10.9.2
Latest Voxengo VST-3 versions

The other odd thing about this is that when Wavelab crashes, there is crash message or info. The program simply closes with no other message.
