I'm doing the quest in the Vegas strip to find out who took the farmers son, so i'm up to the part where I need to talk to the employee in the bathroom/steam room and everytime I go to interact with him its freezes. Any ideas on how to fix this? I have 30 hours of played time and don't wish to start again becasue this is a very similiar issue I had with fall out 3 and why I quit playing that.
