Can not use `Change type` action from editor

[Earewien]

Scenario

• Create a behavior tree in a scene, from editor
• On a node, try to change its type using the Godot Editor menu entry

It fails, saying

  Signal 'child_entered_tree' is already connected to given callable 'Node(BTAction.gd)::_update_cached_children' in that object.
  Signal 'child_exiting_tree' is already connected to given callable 'Node(BTAction.gd)::_update_cached_children' in that object.

I got ride of the error ; the _init method is called twice when trying to switch node type.

Unfortunately, change type is not working, again. There is no error, but nothing happens.
Same issue with other addons (not mine 😂). Godot Engine bug or unimplemented feature ?

Wait and see... Issue will remain opened
