Here's the thing. I was very happy to meet the three paladins at the military base to help me out storm the place. Since I have the Fallout Fixt patch, they also followed me inside which was cool. Actually only two followed me inside, but never mind. I cleared the place and one other paladin died in the process. What was not cool, however, was the fact that EVERY time I got out of elevator on Level 1, the last paladin was standing in my way and I was unable to exit.

Considering that the time was already running out and I tried like 40 times going between L1 and L2 without any luck with him spawning on some other tile, I had no other option but to kill him :/.

Once outside the complex, the other paladin was not showing any hostility at all and we escaped the place together. I thought the saying "What happens in Mariposa Military Base stays in Mariposa Military Base" was in my favor...but guess what.

When I entered Brotherhood to deliver the good news about eradicating the mutants, they turned hostile.

Loading a previous save would not help, since I really need to kill him to get past him, so I'm thinking of opening a save file and change BoS faction relation towards me to not hostile. My question is - how do I do that?

Thanks!

Solved!

Downloaded Vad's FO Save Game Editor from nma forum.

Opened GVARs (global variables) tab

Entry 250:
ENEMY_BROTHERHOOD=1

Changed to 0.

thx had the same problem, that entry 250 saved me alot of searching, some people say this bug is triggered if you talk to rhombus before dealing with the mutant base.
