Tested 10 times using a Vanilla TTW 2.7.2 setup.
Each time I used a brand-new character.
The responses for the Big Guns skill are only partially connected to the survival skill.
Question 5 Response 3 correctly give a result of survival.
however, question 4 response 2 does not provide a feedback count for the survival skill.
it instead, seems to add 1 count to the small guns skill.
because of this it is no longer possible to receive the occupation of laundry cannon operator.
