Safehouse Breach at wish?

[wasabi]

First, hello to everyone and many thanks for gibbed tools and alike.
So, I was looking to start the safehouse breach in a new game+ with the main cases failed (i got the S ending in first run, so this one was to rescue survivors).
Editing "missions.txt", case 7-4 breach had some results: Frank spawns outside SH security room, same with this mission survivors, security doors dissapear and
alarm starts (I get even the mission brief to fix the emergency door)... but not zombies at all. Can you please help me?
What I did was edit mission 7-4 breach start time to the one closer to me (this was "111600" the sex-deviant mission) and changed also the prerequisite mission from 7-3
to "OnceBitten" (remember I failed main storyline).
Thank you for reading.

There you go. You changed the required mission to finish before the case started. So it's loading data from that mission to load in to the next one which seems to get rid of the zombies. Probably cause the original reads more data to spawn the zombies in.

Wow, that was quick! Alright I understand. But I don't see anything related to zombie spawning in previous entries like "Beforebreach, bridge, etc"... I edited 7-4 breach because saw things like "enable zombification", "zombiewarehouse safehouse"... But obviously, you must have a point and Im missing something.
Dude, I edited and repacked like 40+ times.
Is there any way to spawn just one zombie in my current state? I'm thinking of turning all my survivors zombificable and start an outbreak.
EDIT: maybe it would be easier to get to the real breach thing in a new game+, and edit mission values once there. Hopefully there's a way to get all lost survivors there, i'll search forum wisdom.
EDIT 2: There is a way to spawn all survivors in safehouse, indeed. Here, thanks to diszxchat for sharing info: Edit safehouse NPCs
