Reparenting a node, sometimes global_transform is lost

[crystal lynx]

I have a weird issue where when reparenting a node sometimes it gets teleported back to the origin (0,0)
Like the global transform is not being kept
even though I have keep_global_transform as true

Other times it works fine

So my issue was I needed to use call_deferred for some reason
I found this while trying another reparent method someone posted:

https://www.reddit.com/r/godot/comments/mgycy8/preserve_global_position_when_reparenting_child/

I decided to keep their method so I can also reset the rotation to 0 as I only want to preserve the position

func change_parent(child, new_parent):
    call_deferred("_reparent", new_parent, child, child.get_global_transform())


func _reparent(new_parent, node, old_transform):
    node.get_parent().remove_child(node)
    new_parent.add_child(node)
    node.transform = new_parent.get_global_transform().inverse() * old_transform
    node.rotation = 0

It might have been because if the physics ticks lined up badly with the processing ticks or something it would get messed up

Also that call_deferred is deprecated. You can now call Callables deferred-ly directly:```php
_reparent.call_deferred(new_parent, child, child.get_global_transform())

If you have multiple lines you want all to be called deferred-ly, you can wrap them in a lambda and call *that* deferred:```php
(func():
  _reparent(new_parent, child, child.get_global_transform())
  print("right after _reparent!")
).call_deferred()
