1. Time starts changing the moment you open the vault. Maybe the chest isn't the 6th or 7th but the first. 2. Anyone killed atheon while players were still in the portal? 3. Anyone stayed at the blood chest while others completed the whole raid without dying and seeing if the spirit bloom chest changes? Maybe the vault (while it had bloom) was a chest from the present, and then in the future (after atheon) it has different loot. 4. Had everyone completed the raid on hard and normal (so technically future) and seen if anything changes at the start of the raid, such as at the spire?
