Has anybody found a solution for this other than "load a previous save"? I would lose so much stuff if i had to load a prior save. I'm not sure how or when this occured but I am unable to fast travel ANYWHERE.... i've tried everything I can think of and nothing seems to work. I noticed it after i got to the end of Snyth Retention where it asks me to return to father... i open up the pip boy... try to fast travel to the institute.... NOTHING!!! I then try it in another location... again.. NOTHING... move to another location... NOTHING.... "can't fast travel from this location" Bethesda... PLEASE FIX THIS ASAP!!!! the game is basically unplayable... i'm stuck on this quest because there is no other way to enter the institute...

Try the solution found here:
