The goof item below may give away important plot points.
In the scene where Mynce is eaten alive, the Maraisreq creature first rises up from the ground facing the camera. The Maraisreq immediately faces Mynce without turning before it approaches her as Mynce still has her back to the monster. In the next shot, we see that both are immediately facing each other.
It is revealed that Mynce survived being digested by the Maraisreq, but it is never explained how it could have been possible: Mynce would not be able to free herself seeing how Mynce's blades were strapped to her calves and would be impossible to unsheathe in a tightly confined position.
