I'm chasing after the 'Cursebreaker' title for a while, I have 8/11 triumphs done and I went after the secret triumph and you just can't get it cause the boned are not spawning, not the time gated ones and not the non time gated ones, its extremely annoying cause idk if the title is going to be vaulted soon and its already a grind and a pain to get all of the bones, like c'mon its 6 weeks to get them all. It happens to a lot of people and its just not getting fixed.
