Having the same issue here.
The quest was failing before the patch. The day after I saw that 1.04 was supposed to fix this quest.
Seems to bad I had launched the quest before the patch.
Now, like before the patch, as soon as I enter the building the quest auto fail.
I've tried to reach to the npc Max, I see him, standing in position where is holding a gun against his head, except his hand is empty, and I can't do anything with him, I can't interact, no dialog, nothing, and I can just go through him like in a noclip mode.
When I enter the building, I see him as a cross ( dead poeple marker ) on the map.
I guess the patch hasn't done anything as this npc spawn dead or bugged anyway.
Would be cool to have a fix or a console command to fix this by ourselves.
Thanks.
