Trying to get transcendent blessings and have a bounty for one that states "Defeat any Plague of the Well while Ascendant". I've been attempting this casually for a few days and it doesn't seem to register kills. I've been ascendant throughout the whole event, I've popped a tincture right as the bosses spawned, I've made sure I got the final blow and I've tried it on every tier except tier 4. Am I missing something or is this bounty bugged?
