Peculiar behavior of group objects with hide-lock. show-unlock

I've hit a similar, but not identical, issue and have been planning to 
submit a bug report but it's been tricky to extract example code from my 
full project so I haven't got to it yet.

There seems to be an issue with nested lockscreens if one of the locks 
uses a visual effect. My guess is that the one with a visual effect 
seems to corrupt or override the lock count.

The workaround in my current project is to make sure there is only one 
set of lock/unlock commands, the one with the visual effect. Apparently 
that didn't work for you.

My stack doesn't use "show/hide with visual effect" though. Instead I 
"lock screen for visual effect" and then later "unlock screen with 
visual effect." Maybe separating out the command that way would work better.
