Hello, I have had this problem for a couple of days/weeks now. To complete the primal daily Liu Soo's Plea I have to kill fortunate disciples, after whose death river spirit projections should spawn. The problem is these rsps have been spawning before, but now they don't. I've killed dozens of those disciples, with the effect or without, and nothing spawned at all.
Sometimes when I melee attack the disciples (which is difficult, since I'm ep and keep missing) the rsp spawns before the disciple is dead.
