The Solstice event is back in Destiny 2, and along with new armor and weapons, it also brings with it some nasty bugs. One of the bugs requires you to add Kindling to Sunlit Armor via an annoying notification.
BUNGIE WHY!…They MUST listen! – Solstice 2024 Event
Kindling and Sunlit Armor are from last year’s Destiny 2 Solstice event, and they don’t exist in the 2024 version. This year’s armor is the Sublime Armor, while Kindling has been replaced by Incandescence. The Sublime Armor also doesn’t have custom mod slots, unlike the Sunlit Armor.
Here's how to fix the "Add Kindling" notification bug in Destiny 2.
To fix the bug, continue with the Celebrating Solstice quest. After you complete the quest step to reset your Solstice Forge bounties, the tutorial message should disappear and you can begin farming Armor Alloy or event weapons.
