Game Mechanics: Bug with Feign Death (necro)

[Anathuril]

I was fighting a burynai digmaster in frontier mountains at level 32 with a monk.
Another burynai appeared, a rockshaper, and joined the fight, causing me concern.
So, I feign - feign fails - a side issue I will detail later.
While attempting to survive until feign comes back up, I get knocked unconscious.
Feign comes up, and I regain consciousness, and hit the feign again (I use macro).
Feign clearly succeeds, because the macro indicates the targeted mob (digmaster) is indifferent.
The targeted mob then hit me and killed me.

I should note that this bug not only cost me experience, but considerable time in a
corpse run and, of course, in writing this report. Seems I should be able to recover that exp,
but no doubt that is yet another part of the "1999 experience".

Oh - and though feign seems to hardly ever fail when I practice (maybe once in 20 attempts),
it always seems to fail when I am in a battle - interesting!
Cost me a life this time (as it has on several prior occasions).

So, if feign doesn't work or regularly fails when needed, what the hell good is it????

I have included screenshot with the macro, which should answer those that think this is not a bug.
The FD macro was used after the rockshaper hit me for 80 + 14 points.
The failure can be seen by my falling to the ground.
The digmaster is still "scowls at you".
The FD macro was used (a second time) just after "You are conscious again".
The /con in the macro indicates the digmaster is indifferent.
The digmaster then proceeds to hit me for 32 points, killing me.
