Continuity mistake: Episode 1-14, "Heart of Winter". Just before the robbery, Jake throws some water bottles and a flashlight over a small mound into the bushes, to hide them from the thieves. But when Mimi later picks them up, they are much closer to the truck, and on the other side of the mound. In fact, the bottles and flashlight would have been in plain sight for the robbers where she picks them up.
Continuity mistake: In the beginning of the episode when Eric and Jake are riding in the car, Jake asks Eric if the shotgun is loaded, and he says yes. The gun in pointed up towards the roof of the car. The shot changes and the gun is gone, then switches back and it's back on Eric's lap.
