1. What the circumstances were.
Prison break event when I had three prisoners.
My prison layout:

2. What happened.
Prisoners exited the first door, and came into line of sight of the top turret. Turret did not fire. Both traps were hit. Prisoners then moved to the top turret, coming into Line of fire of second turret. No turrets had fired.
Prisoners attacked top turret, destroying it in an explosion.
3. What you expected to happen.
The prisoners to be classified as hostile and fired upon by the turrets.
Yes, I have the same bug.
The turrets just ignore all prisoners during a prison break event.
I have removed all mods and still not working.
It used to work in 1.2 and before.
Thanks for the bug report.
I have confirmed with the devs that this was a deliberate change and is working as intended.
