Currently I'm working through the Heart of Thorns story for the first time. As part of gearing up, I took both a metabolic and a utility primer - the 12 hour versions - then some ascended food and a writ. At first it all worked just fine. Just now, after finishing the Roots of Terror chapter I realized that the ascended food and writ buffs had disappeared. The primers were still there and had more than 9 hours left on them but the food and the writ had just vanished. Is this expected behavior or a bug that needs to be reported?
