I did the Coil for platinum two times; thus, I was inside Chamber of Dreams two times, but I still do not have triumph "A Place of Dreams". First time was inside match-made version. One guy left after 3rd path and other joined. [url=https://www.bungie.net/7/en/Pgcr/14096165576]We had over 140k points[/url]. No triumph. Second time I was with my teammate, Cahir#0814. Match-making was off. At the end of the 3rd path I invited another teammate. [url=https://www.bungie.net/7/en/Pgcr/14101989287]Over 150k points[/url]. Neither me, nor Cahir got this triumph. UPD: I figured it out. Wait for all chests to spawn in this room and only then claim them. Better to claim first right and first left, they give keys for other chests in this room. UPD2: from known issues: [quote]Players are unable to open a Wish chest if they open an armor/weapon chest before it in the Wish room, blocking certain triumphs.[/quote] So open middle chest before chests with armor/weapons.
