Does that work? Can you designate more than one burrow for alert statuses? I didn't think you could, but I also never use alerts...
Yes, you can-I've done it often enough. All you have to do is create an alert, set it to whichever burrows you like and make it a civilian alert at times of need. When you want to turn it off, make the "No training" alert the civilian alert instead of it. If you want, I'll set it up in my turn.
But can you have more than one defensive burrow active? Because it looks like setting up Burrow 1, which is locked in Blue's territory, as the defensive burrow would cause all Red dwarves to freeze in their tracks. Vice versa would apply as well.
Well, I'm fairly certain that you can, but I could be mistaken. If I remember correctly, you basically have to create an alert, and simply select whichever burrows you want the alert to be set to. The selected burrows will be marked with an "A". When you do set the alert to a civilian alert your dwarfs will be limited to the burrows you selected.
I'll be testing this out on this save shortly to see if it actually works.
Edit:Also, about this:
Apparently, some of the "construction crew" can arrive in a migrant wave. They arrive unhappy, as a result of very poor few months under my care. The one that I saw arrived, set labour as "Attending Meeting" and never moved. If this happens again, well... we'll figure it out.
The expedition leader is locked inside the blue team's fortress, right? That's probably why he did not move;ie. he could not path into the fortress. This is why we need a central noble room.
