EA Staff (Retired)I wanted to check if you were still stuck here. You may want to perform other quests and return to this area if the wisp is not spawning for you. I believe it first spawns over the coffeen to the left of the center one.
Hello,
I'm on the quest called "When Plans Align" with no other companion quests and sidequests left, all companions are on Hero of Veilguard, and I've recently tried the braziers again starting from the coffin on the left of the center one (All braziers are lit up after following the wisp), but resolving the puzzle just opened the coffin again without any wisp spawning for the chest.
Unless I've totally missed out on something as a prerequisite, I'm pretty convinced it's a bug and I hope it gets fixed.
