Stage Bos bug on overkill hit

From 0.1 we have bug on boses, when hit too hard like overkill before he can die (because in code is second stage), bos can't die and can't not go to second stage, so map is done uncompleted (failed).
Why we cant report in game maps like we lost from this stupid code bug?
It's so simply to give option to mechanical reset by support.
If its not possible to repair code by your u programers, delete mechanic second stage or give option to reset.
Imo its so stupid think to add more bos with second stage on patch 0.3.

BUMP, FOR ANY SUPPORT RESPOND.

I give u tip
King in the Mists second stage start after u kill first type of bos
so its never have this bug problem. Maybe thats way is better to do with other boses?
