I suspect this has something to do with Reckless Dodge trait…. Sometimes the dodge ends immediately. It has no animation nor normal evade effect, but the small aoe from Reckless Dodge still apply(with aoe animation). This always happened while very close to a foe, especially for those that has large size of collision body. For example, the Searing Effigy of Ferrah path in Citadel of Flame.
