Krosus Log not registering kill

Guild killed krosus right as he broke the bridge. Logs don’t record it as a kill, even though if you look at the damage he is taking overkill dmg when it says encounter was a wipe.

You can see Hump gets the killing blow with an aimed shot then several others have overkill dmg while he is temporarily immune I guess, but it still registered us killing.

Yeah, Blizzard reports that as a wipe (incorrectly). I am looking into an automated workaround for it.

Well my ret paladin would be thrilled for this to occur. She was like my GG parse! Thx
