Others have told you the "better way" to do this but in case you were
curious why it crashes the way you've done it, I'm pretty sure it's
because you aren't using ref_ptr's. Once you set root2 then root is
removed from the scene and the reference count goes to zero. This means
it is deleted.
No, I use ref_ptr, here was just an example . thanks,

Ok. Just that with the code as you have above it would definitely crash
exactly like you describe. If you use ref_ptr's instead then it shouldn't.
