I was being attacked by radroaches and my pregnant dwellers runned for their lives while the men in other rooms runned to the rescue to kill the rads. The pregnant women started getting out of the elevator while the men were getting in, no moviment from there anymore. They got stuck until the other unnarmed dwellers fended off the rads alone. After the fight they stopped forcing their way through each other and the bug was "fixed". Please check it out staff...
