Upon reopening C9.5 the macro has deleted the reverb

So I have created this macro for reverse reverb which includes Roomworks Reverb plugin and it works fine.

Until I reopen C 9.5 and it has removed the Roomworks Reverb plugin from the macro.

Same in C 10.

Any idea why Cubase cannot remember plugins which have been added to macros?

I’d very much like to know this.

Any mods confirm this on your end?
