Has anyone else noticed that sometimes, when using an AOE attack on a group, that as soon as one member of the group dies, the AOE will sometimes immediately end? This is very noticeable with Liquid Lightning and Elemental Blockade. When attacking a group of mobs, I'd say maybe 25% chance that when the first mob dies, the AOE just goes away. I have confirmed this many times on mud crab groups on the beach in Grahtwood. And no, it isn't "the AOE timed out" - the AOE will sometimes just end immediately after being placed when the first mob dies. I have confirmed it's not a graphical bug either as mobs stop taking damage when the AOE disappears.
Am I missing some secret mechanic to how AOE works, or is this just (yet another) bug introduced by DB?
