Losing rings causes repeated `area_set_shape_disabled` errors.

[Sslaxx]

The line this error refers to is get_node("/root/Node2D").add_child(currentRing). This is line 767 of Player_v2.gd.

Replacing this line with get_node ("/root/Node2D").call_deferred ("add_child", currentRing) appears to remove the errors/warnings.
