On scene transitions there are multiple scripts that lose their reference to the "protagonist".
The ones that I know of:
menu.gd
InteractionMangaer.gd
They use the get_tree().get_first_node_in_group("protagonist") to get a reference onready and then lose it eventually, causing errors when for example menu.gd tries to reposition the protagonist.
