The corpses in Heroic missions with collection drops are de-spawning when the chests are opened, thus if someone opens the chest and the collection don't roll then we loose out on the collectables which are very rare. Can you make the bosses drop like 3-4 collection drops each time , so we can get what we have lost and make the corpses not de-spawn after chest is open ? Or just put 4 collection drops in the chests each mission
This will be addressed in today's update. As an example, in the Velketor mission Seeking the Sorceror, collectibles will drop from the restless kobolds and Coldain.
That's the only mission that actually has trash mobs up to kill though. Rest of them only get npcs that the event spawns.
Reading the notes, named in static Kael will drop and normal mobs in static EW will drop the other two sets that are missing.
