Tried searching all over, found some threads that seemed to have the same problem, but all replies ignored the actual problem and gave answers that didn't help.
Ever since my last completed Kuva weapon, I just don't get the light flicker to prompt the spawn of a larvling on Cassini anymore. No, I don't have a Sister or Lich active. No, I don't have to rush to kill enemies after capturing since I don't even get the flickering. No, waiting doesn't help, tried waiting 10 minutes after capturing and all that happened was the dude with a Granum Crown spawned. Tried the mission on Sedna and got the flicker and larvling there, but that mission/map is annoying and takes much longer, not at all good when you're after a specific weapon. The grind is already stupid, no need to make it worse by getting forced out of the best mission for it.
Anyone has any ideas?
