I’m working on the 100% achievement completionist in SC2, I have completed wings of liberty and heart of the swarm but in legacy of the void there is a problem. I have finished all the missions together with all the achievements but for some reason the bonus objective Ulnar is not completed it states that I must complete the Harbringer of oblivion even though the achievement Harbringer of oblivion is it self completed meaning there is something wrong. I have finished that mission but it the bonus objective says otherwise. Please fix this problem for me so I can finally get the 100% completionist.
