Factual error: When Alina stands outside of the door to the banquet hall, waiting to demonstrate her power to the king and queen, there is a modern electronic occupancy sensor on the wall behind her.
Continuity mistake: Alina is trying to escape both the Crows and General Kirigan's men through the streets of the town of Ryevost. While in an alleyway, she kicks in the door to a building, only to still be outside when she emerges from the other side of the door - when she looks back inside of the door she just emerged from, it leads to the interior of a building, not the alley she just came from.
