Reaper not spawning

Ok, so a few hours ago I got my region level to 21. I only have four active rivals, and its been a while but the reaper isnt spawning. I have already gotten a normal rival that I assumed should have been the reaper but it was another hunter. Is there something I am missing? I did the whole thing in single player, I am playing on a very good PC. (laptop if that matters)
