Error: Value 'id_card' is not a boolean

It's being caused by this: https://gitlab.com/voadi/voadi/blob/a041a1e82e7e42b62ed20ac359c34a92e8c5cf6a/data/maps/overworld.lua#L246

To reproduce it, run this at runtime:

game:set_value("cutscene1", 1) game:set_value("stick_chest", true) game:get_item("stick"):set_variant(1) hero:teleport("overworld", "east_beach")

Then talk to Greybeard. Upon receiving the ID card this error happens.
