State of Decay 2: Juggernaut Edition

After defending your homebase in either story arch, you can encounter Diana at her first location in between Jurassic Junction and Marshal(South of the map). It is the dirt road that split into three, you want to head strait up the road then turn left where you see a barn. You will find Diana swarmed by zeds that you must kill and clear out. You can ask her to join your community but she is not a people person and will not join. Search for a AR in the barn for yourself and walk away.

After completing Logan's second Mission you may try and head towards the town of Marshal and enter on the east bridge and she should be near the gas station/Wine and Bovine. She is at the Dirty Bird Expresso, help her out again. You can then ask her to join your community but she will give you the same response.

You will then have to wait and hope to RNJesus that she appears at your base asking to join.

Note: This has happened to me twice where she did not spawn.
First scenario; she did not appear at my base despite me completing her two missions.
Second scenario: her second mission didn't spawn.

I believe that if you keep trying to look for her at her spawn points, the game could bug out. My tip is to use the West Bridge of Marshal just in case you do not want to screw up the mission spawn. Also try not to look for her after you did her first mission, just wait about an hour or two.

If you unlock Diane first mission and the second one doesn't spawn their a couple of steps you can do to unlock. First thing to know you gotta wait a whole day in game for the second encounters estimated time is 2 hours. Second encounter also only happens in the day by my understanding (I could be wrong) over by the dirty bird espresso south west of your base. If she not their she's at her based at the factory husk it would have an enclave population of 1. That is a little bit up north west of the dirty bird. If a whole day and night cycle past since the first encounter and the second mission is not popping up (try to stay away from these 2 places. I did the Cleo drops to pass time since I needed that achievements as well) when day hits and it says a new day drive toward the dirty bird and Diane second encounter should pop if not drive to the factory to see if she there if not drive back to the dirty bird and it will start if she is their you got 2 options and they both suck. 1st option you wait another day/night cycle ( it could be glitch and just wasted another 2 hours) to have it triggered or you the 2nd option is get a horde of zombies it doesn't matter what kind bring them in the factory with Diane and watch them kill her. A dialogue will happen where your character would be like poor girl. But have no fear as these are the only characters you can recruit in the game so they come back (not your 2 starting character or if you already recruit them) wait like 10mins drive to where the first encounter took place at the barn and start the first encounter all over again...

This is more of a guide if your missions are glitch work for all characters
