One challenge to rank up to Guardian Rank 9 is to Claim 2 Titles. I had 1 unlocked already and then unlocked the "Transcendent" title, but it did not count towards the objective. I hoped the act 2 update would include a patch for it today, but my objective is still at 1/2 titles claimed. Really just want the team to be aware of the issue so that it will be fixed, will probably go for another title to get the objective though.
