"When Freedom Calls" Clear Concord of Hostiles bug

[0ber0n812]

Doubtful I'll find a solution any time soon but thought I'd post anyway. Looking online this appears to be a bug that has been around a while. I have never encountered it until now. As soon as I get the power armour on the roof of the museum and grab the minigun no hostiles spawn. No raiders or the deathclaw. The most recommended solution that's suggested is to use console commands to move the quest forward. Having done so though, Preston and his group stay in the top room inside the museum of freedom and are unable to talk to.
I tried resurrecting a dead raider too but that didn't really work. I've found I can progress the main quest through commands so there's no loss there but I'd still like to get Preston as a companion. I tried to activate the "Sanctuary" quest too but although it makes the characters leave the museum they just stand outside the exit without walking to Sanctuary.
If there's anything else I can try I'd appreciate the suggestion but I'm really stumped as to what to do without starting all over again.

After a lot of digging online and working things out I discovered that for some reason either one or more creation club creations can cause quest breaking bugs as early as the very start of the game. The worst during the "When Freedom Calls" quest that I had found. I assumed it was a mod from nexus but after removing the "Horse Power Armour" and "Tunnel Snakes Rule!" creations I was able to progress further in the quest.

I know this is a little late LOL, but I found this workaround in another forum.  Using the console command, click on a raider body and use te command ressurect.  When they come alive, kill them.  The video I saw worked on the first raider they chose but for me, I had to ressurect several and it wasn't until I did it to the leader, Gristle, did the quest complete.
