Continuity mistake: After Sierge has killed the Tsjude behind Aigin, the Tsjude falls on top of Aigin. As Aigin shakes the Tsjude off, you can see the Tsjude's arm down by his waist. As it cuts, his arm is suddenly pointing away from his body. (00:47:35)
Continuity mistake: As Orbes is surrounded by the Tsjudes, they fire their crossbows. As the camera turns to Orbes, we see all the arrows hitting him in the chest. That's impossible because of the Tsjude's positions. Orbes should have arrows hitting him from all angles. (00:50:05)
