Kansas (Gravestone) objective problem

[Ronin]

this is the mission where you get the nuke, defend from the evil muties, kill the 3 commanders, and last but not least 'protect' bisshop

well and that last thing is the problem, for some reason it wont complete that objective, I hold of the attack, killed the 3 commanders (those 2 objectives are met) I talk to bisshop again (yes hes not dead) and then dekker starts debriefing me, goto exit grid

when arriving at exit grid, the guy ends his debrief with the fact that I couldnt complete the mission, as if bisshop is dead.

why wont this protect bisshop objective be completed, did I forget something, should none of the ghouls die? he did sound kind of pissed in the last talk to him, but he still gives the nuke

anyone who knows what seems to be the problem, please help

(maybe it doesnt even matter that dekker says I didnt completely finish the mission)

thanks in advance

to add what dekker debriefs me

".................. long bullshit.......

important part:

Many of graveston's ghouls now rest with their pagan god. while we weren't planning on getting any recruits from them. the bitter bishop refused to give us any information or documentation on the bomb's properties. oud scribes should be able to uncover the device's secrets over time. but now. our other research project will suffer.

Your inability to fully carry out your orders has been documented.

Dismissed."

You didn't "fully carry out your orders" because many ghouls died. Personally, I never bothered to keep any of them but the Bishop alive.
