There's an issue with family object containing sprites with Global turned on.
On layout 1 click on sprite - instance is destroyed and text with objectcount will properly subtract 1.
Now the issue:
- run project from layout 1
- go to layout 2
- go back to layout 1
- click on sprite to destroy it
Objectcount will show proper value (subtract destroyed sprite), but sprite will be still visible. You have to switch layouts to make it go away.
