Here is when I ran verbose:
Leaked instance: RefCounted:<number>
Leaked instance: GDScriptFunctionState:<number>
Leaked instance: WeakRef:<number>
Hint: Leaked instances typically happen when nodes are removed from the scene tree (with `remove_child()`) but not freed (with `free()` or `queue_free()`).
