I'm pretty sure I've glitched my Solstice armor because I can't upgrade it. I had a full set of magnificent Solstice armor when I accidentally deleted my chest piece. I went into my collections and got a new majestic piece and re-did the associated challenges, but couldn't upgrade it at the alter in the tower, even if I was wearing all my other Solstice armor pieces. I got myself a full new set of the majestic armor and re-leveled it incase that was the issue. Unfortunately I'm still unable to meditate at the alter in the tower, even though I have a full set of majestic Solstice armor equipped with all the challenges completed. Am I just out of luck or is there anything I can do?
