Why won't Jarrik the Crusher appear in Mammoth Keep?

I'm doing the quest, "The Crusher's End" were you kill the Bandit leader, Jarrik the Crusher. But in the keep it is only other bandits there, not him. I have searched the entire keep, killed everyone but he is not there. The arrow just points to the center of the main room. How do I fix it?

You're going to want to spawn him manually, in the console enter prid xx11d62b (xx being whatever the id for the Falskaar mod is) then enable, then moveto player and it should spawn him. (I'm not sure if you even need to enable but it's better to do so. I also used resurrect just to be safe.)

For whatever reason, he doesn't seem to spawn properly, and the arrow just points to the rooms centre, but you can spawn him yourself and continue things just fine.
