Unable to speak with the Fixer, after dealing with Guerrero

[VNG]

The very last scene at the landing pad, after talking some sense to Guerrero (both lethal and non-lethal for him ^^), the optional task shows up, "Speak to Fixer". The Fixer himself is very much alive, facepalming on the left side of the pad, but no interraction option appears when targeting him. Although this task gets marked as failed as soon as the Fixer gets a bullet or a stun dart from a someguy named Walthers.

Solved this one, solution is the same as here - i was trying to speak to fixer in block A (red) uniform, reloaded pre-landing pad save, ran through enemies back to the secret closet, changed the uniform to block B's (yellow) and after I've finished the final scene, I was able to speak to Fixer.
P.S. Way to go, devs and QA

Thanks, finding your post helped me out. For anyone else who might have this issue, I'll elaborate on what happened with me.

I originally missed the pre-landing pad part in your post. If you've already done the final confrontation, it seems no outfit switch will allow you to talk to the Fixer. I had to load before the final confrontation. I was in the Yellow Block B uniform at the time. All I needed to do was to go back and switch to the Red Block A uniform, and then trigger the final confrontation. After that point, I was actually able to talk to the Fixer.
