FmodListener2D references get lost

[timoschwarzer]

I have set default_listener_count to 2 and added two FmodListener2D nodes to the tree. One of them has listener_index = 0, the other has listener_index = 1. Both of them have a weight of 0.5 and are not locked.

After some debugging, I noticed that FmodServer.get_listener_transform2d(0) always returns a zero transform.
FmodServer.get_object_attached_to_listener(0) returns some weird [Wrapped:0] object, and FmodServer.get_object_attached_to_listener(1) returns <Object#null>, so something seems to cause listeners[i].gameObj to become invalid.

Replacing these nodes with custom nodes and adding them manually using FmodServer.add_listener(0, self) in GDScript works.

Hello ! Are those listeners added to the scene via the editors, or do you add them programmatically and then set their index ?

[timoschwarzer]

These are two FmodListener2D that are in the main scene. Both have set their index to 0 and 1 respectively.

And you have set them using editor, right ?
