I noticed this happens after reloading my scene (my game reloads the main scene indefinitely with random parameters).
I also noticed that my objects are not "pickable" anymore:
func _input_event(camera, event, pos, normal, shape):
callback not being called anymore.
Also found this error in Android logcat, that i am feel is related to my problem but can't figure it out...
