It has come to my attention that if you flunk the interview to join the Institute, fight your way through tchortists and go to the hole in the floor in the West Wing (which leads to Upper Underrail) you can't actually jump down said hole to get out. It used to make sense in earlier versions since jumping down that hole would've softlocked the main quest before the alternate way in was added. But now that we have Utility Station 6 this restriction should be lifted. If there are concerns about players getting confused an additional prompt that suggests finding another way in could be added.
